A rocket hit a key southern Afghan town Thursday, killing a civilian and wounding five other people, AP quoted a local official as saying. The attack on Lashkar Gah, the capital of the southern Helmand province, follows two other insurgent assaults this week on security force checkpoints ringing this city. Over 80 militants were killed, and three police were wounded in those clashes. The rocket landed on a city street lined with shops, killing a civilian and wounding five other people, said Daud Ahmadi, the spokesman for the provincial governor.
