BBC News reports:
Iraqi cleric and militia leader Moqtada al-Sadr has threatened to take up arms against US troops unless they leave the country by the end of the year.
In a rare interview, he told the BBC he believed US forces would not stick to an agreement to withdraw from Iraq.
The US still has about 46,000 troops in Iraq, due to have withdrawn by January 2012.
On Thursday, tens of thousands of the cleric’s supporters rallied in Baghdad, calling for the Americans to leave.
The Pentagon has been pressing the Iraqi government to decide quickly whether it will ask some to stay on beyond the deadline.
In Sadr City, Moqtada al-Sadr’s Baghdad stronghold, his supporters marched in military formation, their boots trampling on the flags of the US, UK and Israel.
