A van flew off an elevated portion of New York's Bronx River Parkway Sunday afternoon, falling more than 50 feet before landing in a horrific crash that left seven people dead, multiple news outlets reported.

The accident, near the Bronx Zoo, happened at about 12:30 p.m. local time, authorities said. It's not clear what caused the crash.

According to the Associated Press, the van was headed south when "it bounced off the median, crossed all southbound lanes over to the guardrail and fell." The vehicle "flipped off a ramp into a transit facility near the Bronx Zoo," CNN reported. According to NBC's New York affiliate, it was a rail yard.

It was not clear whether all seven of the victims were traveling in the van at the time of the crash. According to the news service, three of the victims were children.

According to NY1, at least one victim was pinned inside the vehicle.

According to the New York Post, all seven victims were traveling in the van when it crashed.

Fire Department spokesman Jim Long told the AP that the victims "were an 84-year-old man; three women, ages 80, 45 and 30; and three girls, ages 12, 10 and 7."

Wooing the young voters crucial to his re-election, President Obama today launched a passionate campaign-style appeal to students as he pressed lawmakers to prevent the cost of college from rising.

Speaking to a rowdy crowd at the University of North Carolina at Chapel Hill, the president said he understands the financial burdens students face. “Michelle and I, we’ve been in your shoes,” Obama said. “We didn’t come from wealthy families.  When we graduated from college and law school, we had a mountain of debt.  When we married, we got poorer together.”

While the president did not call out the presumptive GOP nominee by name, he drew a sharp contrast between his background and that of Mitt Romney, who comes from a wealthier family. “This is something Michelle and I know about firsthand,” Obama said. “I didn’t just read about this… I didn’t just get some talking points about this. I didn’t just get a policy briefing on this.”

“Check this out, all right?  I’m the president of the United States.  We only finished paying off our student loans about eight years ago,” he said to laughter from the crowd of roughly 8,000. “That wasn’t that long ago.”

While young voters still overwhelmingly support the president — Obama enjoys a substantial 60 to 34 percent lead over Romney — their interest has waned since 2008.

According to an NBC/Wall Street Journal poll, 63 percent of 18- to 34-year-olds took a major interest in the election in 2008. Today, just 45 percent have the same level of interest in this presidential election.

Obama is spending Tuesday and Wednesday visiting three key battleground states to push for low-rate college loans, wooing young voters while targeting a financial burden that hits the middle class and threatens the economic recovery.

In North Carolina Obama urged lawmakers to extend a 2007 law that cut student loan rates to 3.4 percent. If Congress does not act, interest rates will double to 6.8 percent on July 1.

“For each year that Congress doesn’t act, the average student with these loans will rack up an additional thousand dollars in debt,” the president said. “That’s basically a tax hike for more than 7 million students across America, more than 160,000 students here in North Carolina alone.”

Obama is expected to make a similar argument at stops in Colorado and Iowa.

While Romney has come out in support of the extension, the president targeted Republican lawmakers who oppose the measure. “Republicans who run Congress right now have not yet said whether or not they’ll stop your rates from doubling.  We’re two months away,” Obama said, asking those watching to call, email or tweet their members of Congress.

The White House maintains the president’s trip this week is purely official business, but it was hard to ignore Obama’s campaign cadence as he riled up what appeared to be a largely supportive crowd.

“The fact is that since most of you were born, tuition and fees at America’s colleges have more than doubled. That forces students like you to take out a lot more loans.  There are fewer grants.  You rack up more debt.  Can I get an amen?” the president asked.

“Amen!” the crowd cheered.

“The average student who borrows to pay for college now graduates with about $25,000 in student loan debt.  That’s the average.  Some are more.  Can I get an amen for that?” Obama asked again.

“Amen!” the students replied.

A strong, long 7.4 earthquake with an epicenter in Guerrero state shook central southern Mexico on Tuesday, swaying buildings in Mexico City and sending frightened workers and residents into the streets.

More than 60 homes were damaged near the epicenter in Ometepec in southern Guerrero state, though there were no reports of death or serious injury. Fear and panic spread as a less powerful, magnitude-5.1 aftershock was also felt in the capital, where there were also no reports of deaths.

Other aftershocks were felt around the borders of Oaxaca and Guerrero states close to the epicenter.

"It was very strong, very substantial," Campos Benitez, hospital director in Ometepec.

Police radio operator Marcos Marroquin said there were preliminary reports of 60 houses damaged in the municipality but only a report of a broken arm.

Telephone service was down in the city and throughout the area where the quake was felt, and some neighborhoods were without power, according to Mexico City Mayor Marcelo Ebrard, who set up a hotline for people to report damage.

About 40 passengers were stranded for a short time on the Mexico City airport air train, but later released. The airport closed for a time but officials said there was no runway damage and they resumed operations.

"I swear I never felt one so strong, I thought the building was going to collapse,'' said Sebastian Herrera, 42, a businessman from a neighborhood hit hard in Mexico's devastating 1985 earthquake, which killed thousands.

Groups of women hugged and cried at Mexico City's Angel of Independence monument, where hundreds of people evacuated from office buildings said they never had felt such a strong earthquake.

Others typed ferociously on their Blackberries. Samantha Rodriguez, a 37-year old environmental consultant, was evacuated from the 11th floor on the Angel Tower office building.

"I thought it was going to pass rapidly but the walls began to thunder and we decided to get out," she said.

Mexico City, built on a lakebed, was badly damaged in 1985 when an 8.0 earthquake killed at least 10,000 people. In past years, Guerrero has suffered several severe earthquakes, including a 7.9 in 1957 which killed an estimated 68 people, and a 7.4 in 1995 which left three dead.

Tuesday's quake was the strongest shaking felt in the capital since a magnitude-6.5 earthquake struck also in Guerrero in December. Officials said at least three people died in Guerrero, but there were no reports of widespread damage.

A magnitude-8.0 quake near Manzanillo on Mexico's central Pacific coast killed 51 people in 1995 and a magintude-7.5 quake killed at least 20 people in the southern state of Oaxaca in 1999.

Victor Flores, an official at the Guerrero emergency management agency, told msnbc.com that initial reports from teams near the epicenter were of damage only to homes built of adobe or other weak construction material.

Aerial teams will follow up,” he added, “but so far no deaths or injuries.”

A person at Acapulco City Hall told NBC News that they felt the quake had no immediate reports of injuries or damages.

No damage was reported in Oaxaca, about 100 miles west-southwest of the epicenter, according to local television. The front desk at the Hotel Real Oaxaca told NBC that the temblor scared residents but there was no damage.

A worker at Rica Pizza in Ometepec, one of the towns nearest to the epicenter, told NBC News that there was no damage to his business but he heard of damage to some other buildings in the area. He said electricity had gone out at his location -- and many of his business neighbors had lost theirs. His phone was working -- though he said there were some businesses without phone service. He also said he had heard lots of ambulance sirens but doesn't have any specifics on injuries.

The quake was followed by several aftershocks, he said.

"It was very strong, but we didn't see anything fall," said Irma Ortiz, who runs a guesthouse in Oaxaca. She said that their telephones are down and that the quake shook them side-to-side.

Celia Galicia, who works at the U.S. consular office in Oaxaca, had just flown in from Mexico City when it hit.

She said there was panic in the airport, and a dash for the doors. But she said that she saw no damage at the airport and no one was hurt. She says one building in downtown Oaxaca appears to be damaged and has been evacuated.

She added that they've had two strong aftershocks, and that in downtown Oaxaca most people are out on the street at this point.

"It started shaking badly," she said.

The White House said President Barack Obama's oldest daughter, Malia, is safe and never was in danger during  the quake. Malia, 13, is on vacation with a school group in southwestern Mexico, according to reports from the region.

Earlier the quake had been reported at 7.9 magnitude. No tsunami was expected.
