Jihadist bombers who attacked Brussels airport and metro last week also searched the internet for information about Belgian Prime Minister Charles Michel's office and home, reports say.
Details were found on a computer dumped in a rubbish bin after the attacks.
Unconfirmed reports suggest it may have contained files with building plans as well as photos of the prime minister's office from the street.
The computer also included a final message from one of the bombers.
In the confused message, one of the airport bombers, Brahim el-Bakraoui, complained of being hunted and not feeling safe any more.
