Lebanon’s Hezbollah supporters hold banners and wave Hezbollah (C) and Palestinian flags (L) during a demonstration against Israel’s military action in Gaza, in front of the United Nations headquarters in Beirut July 18, 2014. Israel stepped up its land offensive in Gaza with artillery, tanks and gunboats on Friday and declared it could “significantly widen” an operation Palestinian officials said was killing ever greater numbers of civilians. Israeli gunboats lit up the sky with their fire before dawn while helicopters fired into the coastal enclave. Hamas fired mortar rounds at the invading troops and rockets across the border at the southern Israeli towns of Ashdod and Ashkelon. REUTERS/ Mohamed Azakir (LEBANON – Tags: POLITICS CIVIL UNREST)
