Obama, September, 2014: "This counterterrorism campaign will be waged through a steady, relentless effort to take out ISIL wherever they exist, using our air power and our support for partner forces on the ground. This strategy of taking out terrorists who threaten us, while supporting partners on the front lines, is one that we have successfully pursued in Yemen and Somalia for years. And it is consistent with the approach I outlined earlier this year: to use force against anyone who threatens America’s core interests, but to mobilize partners wherever possible to address broader challenges to international order.
"Yemeni President Abd-Rabbu Mansour Hadi resigned on Thursday, throwing the volatile Arab country deeper into chaos days after Houthi rebels battled their way into his presidential palace.
Hadi, a key counter-terrorism ally of the United States, stood down abruptly shortly after Prime Minister Khaled Baha had offered his government's resignation, saying it did not want to be dragged into "an unconstructive political maze".
This was an apparent reference to a stand-off between Hadi and the Shi'ite Muslim Houthi movement which has been holding the president a virtual prisoner in his own official residence.
"We apologize to you personally and to the honorable chamber and to the Yemeni people after we reached a dead end," a government spokesman quoted Hadi's resignation letter as saying.
It was addressed to the speaker of parliament, who becomes interim head of state under the constitution.
Sultan al-Atwani, one of Hadi's advisors told Reuters he had resigned after pressure and threats from the Houthis. He said parliament would meet on Saturday to decide whether to accept or reject it.
Hadi's decision marked an abrupt turnaround from Wednesday, when he said he was ready to accept Houthi demands for a bigger stake in constitutional and political arrangements.
That announcement had appeared to ease worsening differences between him and the Houthis, whose rise to power has placed predominantly Sunni Yemen within a wider sectarian struggle fought by proxies of Riyadh and Tehran in parts of the Middle East.
The Houthis' defeat of the presidential guards had already added to disarray in a country where the United States is also carrying out drone strikes against one of the most powerful branches of al Qaeda."
