Afghan policemen stand guard near the entrance gate of the presidential palace in Kabul, Afghanistan Tuesday, June 25, 2013 following an attack. Suicide attackers blew up a car bomb and battled security forces outside Afghanistan's presidential palace Tuesday after infiltrating one of the most secure areas of the capital. The Taliban claimed responsibility for the attack that came as reporters were gathering for a news event on Afghan youth at which President Hamid Karzai was expected to talk about ongoing efforts to open peace talks with the militant group.
