As curfew continued for the 45th day in Srinagar, Prime Minister Narendra Modi on Monday met a delegation of opposition parties from Kashmir who warned that a continuing law and order problem and unrest in the state will only alienate the people further.The delegation -- led by former Chief Minister Omar Abdullah -- also submitted to the prime minister a memorandum that demanded an immediate ban on the use of pellet guns in the troubled state.The meeting came a day after the delegation met Congress Vice President Rahul Gandhi here on Sunday to discuss ways to contain the prevailing unrest in the Kashmir Valley.The valley has been crippled by a curfew which was imposed since July 9 following the the killing of top militant, Burhan Wani, in a gunfight with the security forces and a call by separatists for a shutdown in protest.Over 65 people have died in clashes with security forces.
