Mourners pray near the coffin of Lieutenant Colonel Nour Eddine al-Jamal, who was killed during Sunday's fighting between Lebanese army soldiers and Islamist militants in Arsal, during his funeral in the Sunni Beirut district of Tariq al-Jadideh August 4, 2014. The Lebanese army advanced on Monday into a border town attacked by Islamists at the weekend in the most serious spillover of the three-year-old Syrian civil war into Lebanon. The military pounded areas around the town of Arsal with artillery for a third day in a bid to expel the fighters identified by the army as members of the Nusra Front and the Islamic State, which has seized wide areas of Syria and Iraq.
