At least four people were killed and five seriously injured when a small plane crashed into a building at an airport in the US state of Kansas, officials say.
The twin-engine aircraft lost engine power shortly after takeoff on Thursday and crashed into a building while attempting to return to the runway at the Wichita Mid-Continent Airport, the Federal Aviation Administration said.
Five people were taken to hospital with serious injuries and rescue crews were still searching for four people who were inside the building, city officials said in a statement.
There were about 100 people in the building, which houses the local base of training company FlightSafety International, when it was struck in the morning hours, police said.
One person was aboard the Beechcraft King Air 200 series aircraft, the airport said in a Twitter update.

The airport said the safety instruction building struck sustained "serious damage, including the collapse of walls and ceilings."
The plane hit the top of the building and the crash caused a large fire that took firefighters hours to control.
Firefighters were evacuated from the building after it was deemed unstable, officials said.
The airport remains open and some flights were delayed.
