Karzai 'to review foreign forces'

Afghan president Hamid Karzai has said that he will review agreements with foreign forces operating in Afghanistan if he is re-elected.

He said he would make international forces sign an agreement governing how they operate, in an effort to limit civilian casualties.

President Karzai is seeking re-election in next month's presidential poll.

The Afghan government has long been concerned about the civilian death toll as foreign troops battle insurgents.
