omersukrugoksu/iStock(LONDON) — Four Americans were killed Sunday night when their helicopter crashed on a remote island in northern Kenya, authorities said.
Their Kenyan pilot also was killed.

The helicopter went down around 8 p.m. local time at Central Island National Park, which sits on a small volcanic island in the middle of Lake Turkana, according to a statement from Kenya's National Police Service.
The chopper was one of two that had landed on the island earlier in the day at Lobolo tented camp, Kenyan police said.
The cause of the crash is unknown and the victims' identities will be released once their relatives have been notified, Kenyan police said.
A spokesperson for the U.S. Embassy in Kenya, who confirmed that four Americans were among the dead, told ABC News they're aware of the crash and are communicating with Kenyan authorities.
A spokesperson for the U.S. Department of State did not immediately respond to ABC News' request for comment Monday morning.
