US forces are today making house-to-house searches for Mullah Omar around Baghran in southern Helmand province, a remote, mountainous region 100 miles north-west of Kandahar, Omar's powerbase until he abandoned it to local chieftains on 7 December. The moves comes despite Afghan minister for reconstruction, Amin Farhang, telling a German television programme last night: "I have heard that he was arrested but more I do not know."
