French authorities say a 10-day search of the beaches and coastal waters off Reunion island in the Indian Ocean has turned up no sign of missing Malaysia Airlines Flight 370.

Searchers scoured nearly 4,000 square miles (10,360 square kilometers) of ocean using a plane, helicopters and a ship but found “nothing suspected of having any connection to a plane,” local authorities said in a statement Monday.

Nearly 200 police on foot patrols also searched nearly the entire east coast of the island. Several objects have already been sent for further examination.

A wing fragment found on the island last month was the first solid evidence of the fate of the plane that disappeared March 8, 2014, with 239 people aboard.
