A family of five riding on a motorbike - including three young children - hit a roadside bomb in southern Afghanistan on Tuesday that killed all five, a police official said, while 20 Taliban fighters were killed in a clash. The family had been heading toward Tirin Kot, the provincial capital of Uruzgan province, to buy new clothes for the upcoming Muslim holiday of Eid, said provincial police chief Juma Gul Himat. The father and mother were accompanied by their two boys, ages 5 and 7, and their 2-year-old daughter. The road they were on is frequently patrolled by NATO troops, Himat said. He blamed Taliban insurgents for the deaths.
