The Associated Press reported earlier this week:

Tribal militias allied with the government helped block a Taliban advance in this corner of northwest Pakistan close to the Afghan border, but their success has come at a price: the empowerment of untrained, unaccountable private armies that could yet emerge as a threat of their own.

Tensions are emerging between authorities and the dozens of militias that they helped to create predominantly in and near the northwest tribal regions. Operating from fortress-like compounds with anti-aircraft guns on the roofs, the militiamen have made it clear that the state now owes them for their sacrifices. They show photos on their cell phones of Taliban they killed and point to the scrubland outside, with graves of relatives who died in the fight.

The leader of the largest militia near the town of Matani, a wealthy landowner named Dilawar Khan, warns that he will stop cooperating with police unless he gets more money and weapons from authorities. Speaking to The Associated Press, he adds what could be a veiled threat to join the militants.

“Time and time again, the Taliban have contacted us, urging us to change sides,” he said.

The New York Times now reports:

Rival militant organizations on both sides of the Afghanistan-Pakistan border have increasingly been teaming up in deadly raids, in what military and intelligence officials say is the insurgents’ latest attempt to regain the initiative after months of withering attacks from American and allied forces.

New intelligence assessments from the region assert that insurgent factions now are setting aside their historic rivalries to behave like “a syndicate,” joining forces in ways not seen before. After one recent attack on a remote base in eastern Afghanistan, a check of the dead insurgents found evidence that the fighters were from three different factions, military officials said.

In the past, these insurgent groups have been seen as sharing ideology and inspiration, but less often plans for specific missions.

Now the intelligence assessments offer evidence of a worrisome new trend in which extremist commanders and their insurgent organizations are coordinating attacks and even combining their foot soldiers into patchwork patrols sent to carry out specific raids.
