this is about the attack that took place in lahore.... the sri lankan cricket team was attacked by 12 gunmen in lahore....5 of the sri lankan crickerters were injured... captain mahela with some minor injuries, sanga a sharpenal in his shoulder, and mendis's head and neck was wounded by some sharpnels. paranavithana (tharanga) had a bullet wound on his chest and samaraweera had a bullet wound on his leg... tharanga and samaraweera's injuries are a bit serious... but now they are all fine.. MY QUESTION IS, WHO WERE THESE ATTACKERS ? GIVE REASON TO YOUR ANSWER. and finally, i bless the sri lankan cricket team with all the best and hope they will recover from their injuries soon... they are my role models and they are like everything for me... i play cricket too... and i'm a sri lankan.... LET'S HOPE THAT THESE TERRORIST ACTIVITIES WONT HAPPEN AGAIN... AND WHOEVER DID THIS, **** 'EM.... GOD BLESS THE SRI LANKAN CRICKET TEAM AND SRI LANKA...
