A U.S. military Osprey aircraft crashed into the ocean near Japan’s Yakushima island on Wednesday with eight people on board, Japan’s coast guard said. The crash happened at around 2:47 p.m. local time, with local residents reporting the aircraft had fire blowing from its left engine as it fell into the sea, Japanese broadcaster MBC reported.

The coast guard received an emergency call from a fishing boat near the crash site off Yakushima, an island south of Kagoshima on the southern main island of Kyushu. It was not immediately clear which U.S. base the Osprey belonged to, but it was believed to be heading from Iwakuni to Okinawa.

In August, a U.S. Osprey crashed off the coast of northern Australia while transporting troops during a routine military exercise, killing three U.S. Marines. Another crash-landed in the ocean off Japan’s southern island of Okinawa in December 2016, prompting a temporary U.S. military grounding of the aircraft.
