An Afghan intelligence officer was killed Saturday in a bomb attack at his home in eastern Afghanistan, an official said. "Mohammad Sharif, deputy provincial director of the National Directorate of Security (NDS), was in his home in Want Waigal district on leave when the incident took place," Mohammad Zahir Bahand, the governor's spokesman in Nooristan province, said. "Nobody else was hurt in the incident," Bahand told dpa, blaming Taliban insurgents for the attack. He said it was not clear how the militants got into his home and left the bomb there. In northern Faryab province, 15 people including a district police chief were injured after a bomb planted in a motorcycle exploded, provincial spokesman Ahmad Javed Bedar said. Nobody claimed responsibility for either attack.
