Lashkar Gah (Afghanistan) - Twenty people were killed Thursday when a powerful car bomb struck a bank in Afghanistan's Lashkar Gah city as government employees were queuing to withdraw salaries, the latest bloody attack during the holy month of Ramadan. At least 50 wounded people were rushed to hospital after the bombing at New Kabul Bank which upturned vehicles, left the area littered with charred debris and sent a plume of smoke rising in the sky. No group has claimed responsibility for the brazen attack, but it comes as the Taliban ramp up their nationwide spring offensive despite government calls for a ceasefire during Ramadan. "The blast killed 20 people and left 50 others wounded, both civilians and military officials," government spokesman Omar Zwak said, warning that the toll could rise.
