Masked gunman opened fire on the Sri Lankan cricket team's bus in Lahore Tuesday, killing at least eight people and wounding six Sri Lankan players, officials said. Lahore police chief Habib-ur Rehman said 12 gunmen attacked the convoy near Lahore's Gaddafi stadium with rockets, hand grenades and automatic weapons and were involved in a 25-minute shoot-out with the security forces. "They appeared to be well-trained terrorists. They came on rickshaws," he told reporters. A police official said two civilians and six police officers who were guarding the players were killed in the attack which happened as the team was heading for the third day's play in the second Test against Pakistan. Television footage of several gunmen creeping through the trees, crouching to aim their kalashnikovs then running onto the next target were aired by a private TV channel. Crystals of broken glass littered the road next to a gun cartridge and an empty rocket-propelled grenade launcher. A police motorbike was shown crashed sideways into the road at the Liberty Chowk (roundabout) in Lahore. Bullet holes ripped through the windscreen of another vehicle and a white car was shown smashed headlong into the roundabout as nervous security officers guarded the site. Sri Lankan authorities said six players were believed to have been wounded. In Sri Lanka, Sports Minister Gamini Lokuge said Tharanga Paranavitana and Thilan Samaraweera had been taken to hospital in Lahore. Sri Lankan skipper Mahela Jayawardena was also slightly wounded in the foot, his father told a Sri Lankan local television station after speaking with his son by telephone. Samaraweera is one of Sri Lanka's leading players. He became only the seventh batsmen in Test cricket to notch a double hundred in consecutive matches on Monday, scoring 214 after a 231 in the drawn first Test.
