WASHINGTON (Reuters) - Investigators examining an explosion that blew a hole in a Somali airliner last week believe the damage was caused by a bomb hidden in a laptop computer, U.S. officials said on Monday.

The officials said investigators believe the bomber had some type of connection to Daallo Airlines or airport personnel.
