YANGON, Myanmar — Searchers found bodies and debris on Thursday from a military transport plane that disappeared with 122 people on board shortly after taking off Wednesday afternoon from an air base in southern Myanmar, military officials said.

The plane was carrying relatives of Myanmar soldiers, including children, as well as 14 crew members, and there was no word yet on whether there were any survivors.

The plane was found in the Andaman Sea about 40 miles from Myeik Air Base on Thursday morning. The bodies of 10 people have been found, military officials said.

The navy and air force had mobilized ships and planes to search for the aircraft in the area near the base, about 350 miles south of the country’s commercial capital, Yangon, the office of Senior Gen. Min Aung Hlaing said in a statement. The plane, a Chinese-made Y-8, was en route from the base to Yangon when it disappeared.
