BEIRUT — Lebanese police shot dead notorious Islamist militant Osama Mansour and another man in the northern city of Tripoli Thursday evening, state media reported.

Mansour was wearing an explosives belt during the clash, the report said. A photo attached to the report allegedly shows the two militants dead inside a car.

Four others were arrested after the shootout, it added.

Both Mansour and Nather were carrying fake identity cards, according to Elnashra news site. Other reports said the shootout occured in the Zahrieh area of Tripoli.

Elnashra said a grenade was detonated and gunfire was heard near al-Asmar Square in the neighborhood of Bab al-Tebbaneh, where Mansour’s relatives live.
