"Reports about attack having being carried out by terrorists of internationally proscribed Haqqani Network are a matter of serious concern and bring to fore once again the need to effectively deal with safe havens and sanctuaries that these terrorists find in our shared neighbourhood," the statement added.
Afghan President Ashraf Ghani on Sunday condemned the attack and called for regional and international cooperation against terrorism.
"I commend the Afghan Forces for their bravery and professional action of rescuing over 100 civilians and killing all terrorists in the insane attack on Intercontinental Hotel in Kabul. I condemn the attack and condole with the victim families," Abdullah wrote on Twitter.
According to the Interior Ministry spokesperson Najib Danish, around 100 guests and staffers were rescued, of which 16 of them were foreign nationals. He said all those who had died or were wounded had been Afghan nationals. The Interior Ministry also dismissed reports of a hostage situation.
The Taliban claimed responsibility for the attack.
