LONDON (AP) — A British delivery driver has been convicted of plotting to attack American military personnel in the U.K.

A jury on Friday found Junead Khan guilty of preparing an act of terrorism. The 25-year-old's work for a pharmaceutical firm took him past U.S. air bases in eastern England.

Prosecutors said Khan, who was arrested in July, had exchanged online messages with an Islamic State group fighter in Syria. They discussed attacking military personnel after faking a road accident.

When police raided Khan's home, they found an IS-style black flag and a laptop containing an article from an al-Qaida magazine entitled "Make a bomb in the kitchen of your mom."

Khan and his 23-year-old uncle Shazib Khan were also convicted at Kingston Crown Court of preparing to join IS militants in Syria.
