From the Beeb:

At least 44 people have died in fierce fighting in Pakistan's tribal region of South Waziristan, officials say.

The fighting took place after heavily armed local tribesmen began to act on a tribal council edict to drive out foreign militants linked to al-Qaeda.

That's the ongoing news. This is the interesting part:

The government has signed peace deals in South and North Waziristan in which the tribal elders have agreed to disarm or evict their foreign guests and to stop militants crossing the border to fight foreign troops in Afghanistan.

Officials say the fighting shows this strategy is working but some observers believe the government has helped instigate the battles by, for instance, spreading negative propaganda about the Uzbeks.

Local tribesmen have also accused the Uzbeks of not respecting their culture.

Locals report that soldiers have been helping the tribesmen, although the army denies this.

There are also some tribesmen fighting alongside the Uzbeks.

The question left unanswered to me is whether the clashes with the Uzbeks has any impact on the Waziristan Pashtun tribesmen's relationships with their Taliban brethern on the other side of the Durrand Line.
