BERLIN — Police arrested a 22-year-old Syrian refugee on Monday suspected of planning a bomb attack in Germany.

Jaber al-Bakr was arrested after being on the run since Saturday. He fled an apartment in the eastern city of Leipzig, where police found explosive materials. "Tired but overjoyed: we captured the terror suspect," police said.

Al-Bakr was granted asylum last year — part of a wave of nearly 900,000 people who arrived in Germany after fleeing conflicts in the Middle East and North Africa.

German media reported he may have planned to target one of Berlin's airports.

Police are trying to determine whether the bomb-making materials found in two apartments in Leipzig are similar to those used in attacks in Brussels and Paris.

Germany's anti-immigrant Alternative for Germany political party has won a string of recent state elections amid a surge in concerns about terrorism.
