Two Libyan traffic policemen were seriously wounded on Wednesday when a bomb exploded in front of their station in the eastern city of Benghazi, a security source told AFP.
"The explosion went off when they stopped their vehicle in front of the station. The car exploded and the two traffic policemen aboard were seriously hurt," added the source.
Security services were investigating to determine if the bomb was planted inside the car or placed in front of the station, an AFP journalist at the scene said.
Benghazi, cradle of the 2011 revolt that toppled veteran dictator Muammar Gaddafi, has recently witnessed several explosions and a wave of attacks targeting policemen and military officers.
The new authorities, who are struggling to rebuild the national army and form a professional police, have failed to bring the perpetrators to justice.
On September 11, the US consulate in Benghazi was the target of an attack – attributed to Islamic extremists – that killed four Americans, including Ambassador Chris Stevens.
