Forming a government in Iraq is "critical" for the country's stability, according to US Secretary of State John Kerry.
He said: "The government formation process is critical in terms of sustaining stability and calm in Iraq."
He added that he hoped Iraqi Prime Minister Nour Al-Maliki would not "stir the waters" in allowing this process to move forward.
Special forces loyal to Al-Maliki have been deployed in strategic areas of Baghdad, police said, after he gave a tough speech on television indicating he would not cave in to pressure to drop his bid for a third term.
But Kerry said "there will be little international support of any kind whatsoever for anything that deviates from the legitimate constitution process that is in place and being worked on now."
