Iraq crisis: John Kerry in Baghdad as Isis seizes more towns
US Secretary of State John Kerry has arrived in Iraq's capital, Baghdad, as Sunni insurgents expand their control of towns across north-western Iraq.
On Sunday rebels - spearheaded by Isis militants - captured border crossings to Syria and Jordan.
The strategically important airport in the northern Tal Afar has also fallen.
The town controls the main road from the Syrian border to Mosul, Iraq's second biggest city, which was captured by the rebels two weeks ago.
Officials said the rebels of the Islamic State in Iraq and the Levant took two key crossings in Anbar on Sunday, a day after seizing one at Qaim, a town in the province that borders Syria.
The capture of Tal Afar airport is a blow to the government as they were hoping to use it as a springboard to recapture the city of Mosul, says the BBC's Jim Muir in northern Iraq.
