Iran is secretly allying with al-Qaeda and Sunni insurgents to launch a major summer offensive against the US in Iraq, reports the Guardian. The goal is to trigger a political mutiny in Congress to force a withdrawal of US troops. Iran had previously been linked to Shia militias but had not collaborated with Sunnis.
The switch in tactics, US officials tell the Guardian, comes as Tehran steps up contacts across the board to put pressure on the Americans. "They're betting on all the horses in the race, even on people they fundamentally don't trust," says a senior administration official in Washington.
