WASHINGTON, DC (NBC) - US airstrikes in Iraq could continue this week.
President Obama said it will be a long term project that now includes more than humanitarian aid.
The Isis threat is spreading, and US lawmakers now fear the terrorist group could move it's target.
The administration says there are no signs of a US aimed attack, but involvement is necessary to curb that risk.
Over the weekend, more humanitarian airdrops for Yazidi Christians stranded on Sunjar Mountain, receiving thousands of pounds of food and water.
The state department says it's pulling out some American personnel in Erbil, citing an abundance of caution amid intense fighting and will explore options for evacuating stranded refugees.
Embattled Iraqi Prime Minister Nouri al-Maliki spoke publicly for the first time Sunday since the US airstrikes.
He says he will not step down.
The president promises no US troops on the ground.
Meanwhile in Iraq, a parliament session to discuss who will lead Iraq's new government was scheduled for Monday, but it's been postponed.
