An explosion hit a bus carrying passengers as well as military personnel Wednesday in the northern port city of Tripoli, killing at least five people and wounding another 10, Lebanese security sources said.
The explosion occurred in the banking street of the Tal neighbourhood of Tripoli, the sources said.
Ambulances with wailing sirens were seen rushing to the area while Lebanese army soldiers cordoned off the area, dpa reported.
The sources said the explosion took place during rush hour as the street was full of people heading to work.
Tripoli has witnessed sectarian clashes in the past weeks that has killed and wounded dozens of people.
The city is also close to the Palestinian refugee camp of Nahr el-Bared, which witnessed deadly clashes last year between Lebanese troops and members of the al-Qaeda-inspired group Fatah al Islam.
