A Lebanese army military post is pictured empty as soldiers hide from snipers at the Sunni Muslim Bab al-Tebbaneh neighbourhood in Tripoli, northern Lebanon March 18, 2014. Tensions between the Sunni Muslim majority and small Alawite community in Lebanon's second city have festered for decades, but the long-standing rivalry has worsened because of the sectarian war raging in neighbouring Syria, where a Sunni-led uprising is seeking to overthrow the Alawite president.
