A deadly attack on the Sri Lankan cricket team in the Pakistani city of Lahore on Tuesday was likely the work of "well-trained terrorists," its police chief said. "There were 12 masked gunmen," Habib-ur Rehman told reporters, adding that police battled against the assailants for about 25 minutes. "They appeared to be well-trained terrorists. They came on rickshaws. They were armed with rockets, hand grenades, kalashnikovs." He said five policemen were killed in the gun attack which also wounded at least three Sri Lankan players. "Five policemen who were providing protection to the team sacrificed their lives," he added.
