The pilots of the Ethiopian Airline plane that crashed in March with the loss of 157 lives were not at fault, the airline's chief executive has said.

Criticisms of the crew's actions were "seriously misinformed" Tewolde GebreMariam told the BBC.

He was responding to claims from a US congressman that mistakes by the pilots were a factor in the aircraft's failure.

The Boeing 737 Max went down just six minutes after take-off in Addis Ababa.
