Karzai blames Afghan attacks on intelligence failures
President Hamid Karzai of Afghanistan has blamed Sunday's militant attacks on intelligence failures by both Nato and Afghan forces.
In his first response to the attacks, Mr Karzai praised the performance of the Afghan security forces.
He said they had proved themselves capable of defending their country.
Officials say 51 people died in the fighting in Kabul and elsewhere: four civilians, 11 members of the security forces and 36 insurgents.
