(CNN) -- Rescuers on Tuesday spotted the wreckage of a Yemeni plane that crashed in the Indian Ocean off the island nation of Comoros, Comoros Vice President Idi Nadhoim said.

The plane, carrying more than 150 people, was en route to Moroni, the capital of Comoros, from Yemen's capital, Sanaa.

A reconnaissance plane spotted traces of the jet in waters off the town of Mitsamiouli, Nadhoim said.

"There were no sign of survivors," he said. "There are a few bodies floating and there is a lot (of) debris floating around."

The crash occurred as the plane approached the airport in Hahaya. The plane tried to land, but couldn't, and then U-turned before it crashed, Nadhoim said.

Officials did not know why the plane could not land, he added.

There were 142 passengers and 11 crew members aboard, Yemenia Air officials said.

Nadhoim offered another figure, saying there were 147 passengers.

Flight 626 left Sanaa at 9:30 p.m. (2:30 p.m. ET) for what was expected to be a four-and-a-half-hour flight. The airline has three regular flights a week to Moroni, off the east coast of Africa, about 2,900 km (1,800 miles) south of Yemen.

Most of the passengers aboard the Airbus A310 were Comoran, an official at Sanaa's international airport told CNN.

There was no indication of foul play behind the crash, the official said.

The crash is the second involving an Airbus aircraft in a month. On June 1, an Air France Airbus A330 crashed off Brazil while en route from Rio de Janeiro to Paris, France. All 228 aboard are presumed dead. The cause remains under investigation.
