Sistani throws in the sponge

This one belongs in the 'bad news' file:

The most influential moderate Shia leader in Iraq has abandoned attempts to restrain his followers, admitting that there is nothing he can do to prevent the country sliding towards civil war.

Aides say Grand Ayatollah Ali al-Sistani is angry and disappointed that Shias are ignoring his calls for calm and are switching their allegiance in their thousands to more militant groups which promise protection from Sunni violence and revenge for attacks.

"I will not be a political leader any more," he told aides. "I am only happy to receive questions about religious matters."

It is a devastating blow to the remaining hopes for a peaceful solution in Iraq and spells trouble for British forces, who are based in and around the Shia stronghold of Basra.
