The Lebanese military began a crackdown on violence in the northern city of Tripoli on Thursday afternoon, after ongoing battles killed a 13-year-old boy and left dozens more injured. Abdel Rahim Mohammad Hamad was killed in ongoing skirmishes between pro and anti Syrian militias in the city, the National News Agency said. Prime Minister Najib Mikati called on security forces to erect checkpoints in Tripoli on Thursday and said they should arrest anyone carrying arms in public. The army has subsequently deployed in new areas and in greater numbers including Tabbaneh and Jabal Mohsen, an Al-Akhbar correspondent in Tripoli said.
