BJP today said, the arrest of a Pakistani national in Jammu and Kashmir again proves that the neighbouring country is the epicentre of terrorism. <br/><br/>Talking to reporters in New Delhi, senior party leader and Union Minister Ravi Shankar Prasad said, the recent comments of a former head of Pakistan's investigation agency also substantiates New Delhi's claim about cross-border terrorism. <br/><br/>A former head of the Federal Investigation Agency had said that 26/11 Mumbai attacks were planned and launched from Pakistan. Mr. Prasad said it is a serious matter and Islamabad will have to answer it. <br/><br/>The Minister also lauded the role of security forces in foiling the terrorist bid in Udhampur in which one militant was killed and one captured.
