OUTSKIRTS OF ARSAL Lebanon (Reuters) - 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, and the Beirut government said the deadly assault would not go unpunished.
With army reinforcements arriving in Arsal, Prime Minister Tammam Salam, a Sunni Muslim, said there could be no political deal with gunmen identified as members of the Nusra Front and the Islamic State, which has seized parts of Syria and Iraq.
