KABUL (AFP) - Afghan Taliban leader Mullah Omar urged his fighters to avoid civilian casualties amid a rising toll of insurgent killing in a message released on the Talibans website Friday. Omar was also quoted as saying he believed conflicts such as the decade-long Afghan war were resolved by 'realisation and understanding, while again urging the immediate withdrawal of all foreign troops from Afghanistan. The United States and other nations fighting the war say combat operations will not cease until the end of 2014, and a substantial training and mentoring mission for Afghan forces will remain after that. Do not wrongly pester and daunt anyone by the barrel of the gun, the English language statement in Omars name said. The Mujahideen have to take every step to protect the lives and wealth of ordinary people. The statement, issued to mark Eidul Azha warned of punishments under Islamic law for fighters responsible for civilian deaths. The elusive, one-eyed Omar has not been seen in public since 2001. In July, the Taliban accused the US of hacking into their mobile phones to send a text message to journalists claiming he was dead. He was also quoted in the statement as saying that the resolution to all conflicts and tribulations resides in realisation and understanding without giving further details. Some commentators interpreted a previous message by Omar in August as signalling a shift towards a greater willingness to talk peace. But any hopes for a negotiated settlement to the bloody war were seriously damaged by Septembers murder of President Hamid Karzais peace envoy Burhanuddin Rabbani by a supposed Taliban peace envoy.
