Where is Mullah Omar?

Where is Mullah Omar? Even senior members of the Taliban don't seem to know his whereabouts, according to sources. They say he disappeared two months ago. Can there be any connection between this event and Pakistan's determination to play a key role in any negotiations over the ending of hostilities in Afghanistan? The same sources say that many senior Taliban figures are now in favour of a negotiated end to the fighting, adding that Sirajuddin Haqqani met with Afghan President Hamid Karzai during the summer in the south of the country.
