Clashes erupted in Sirte on Thursday when IS militants attacked a civilian's house in the city center to arrest a wanted man.

IS militants stormed the second residential district early in the morning to arrest a man named Khaled Al-Wirffalli, who is suspected of being the secrete sniper who killed several IS militants. Al-Wirffalli refused to surrender and exchanged fire with the attackers forcing them to retreat. Later, some of Al-Wirffalli's armed neighbours joined him to defend their district. 

Sources said the IS group has cordoned off the entire district and launched a massive attack on Al-Wirffalli's house. There are conflicting reports about the fate of Al-Wirffalli. Some news said he was killed in the exchange of fire with IS militants, while other news indicated that the exchange of fire is still ongoing.
