IRAQ and SYRIA

Tensions are high between U.S.-led coalition members, Iraq and Saudi Arabia, following comments from Iraqi Prime Minister Haider al-Abadi about the air campaign in Yemen, forcing the Obama administration into a challenging position as it tries to keep intact a diverse coalition against the Islamic State. [New York Times’ Michael R. Gordon and Eric Schmitt]

Congress is “hang[ing] back” on considering the administration’s proposed AUMF against the Islamic State, with no hearings being scheduled by the Senate Foreign Relations Committee and limited support from lawmakers for the proposal. [Wall Street Journal’s Kristina Peterson]  Conversely, Sen. Tim Kaine said the Committee has not given up on passing a resolution, disagreeing with recent comments to the contrary made by House Majority Leader Kevin McCarthy. [The Hill’s Martin Matishak]

U.S.-led airstrikes continue. Coalition military forces carried out six airstrikes against Islamic State targets in Syria between 8am April 14 and 8am April 15. Separately, coalition military forces conducted 17 strikes against targets in Iraq. [Central Command]

The Economist comments on the Islamic State’s recent gains in Syria, suggesting that the “new IS tactics expose the latent contradiction in America’s strategy,” drawing a distinction without a difference between Iraq and Syria.

The jihadist group which has seized the most territory in the Arab world over the past six months is al-Qaeda, despite media attention focusing on the Islamic State.

NBC chief foreign correspondent Richard Engel published a statement yesterday revising details pertaining to his kidnapping along with five colleagues in Syria in 2012. Engel said that it was likely that they had been abducted by a Sunni militant group, rather than forces affiliated with the Assad government as was originally believed.

YEMEN

The UN special envoy to Yemen has said that he will resign. Jamal Benomar made the announcement yesterday following strong criticism of his failure to achieve a political transition in the country.

[Wall Street Journal’s Jay Solomon and Carol E. Lee]  Abadi also put the U.S. in a difficult position by saying that President Obama had agreed with his views on the situation, a suggestion quickly put down by the White House who are finding themselves increasingly “caught between two allies,” report Lara Jakes and Paul McLeary. [Foreign Policy]

Former Yemeni President Ali Abdullah Saleh requested safe exit for himself and his family from Arab Gulf states. These requests have been denied, according to sources familiar with the subject. [Al Arabiya News]

The U.S. has urged Iran to stop sending weapons and support to Houthi rebels; a senior State Department official accused the Shi’ite nation of attempting to expand its influence in Yemen and assert its dominance over Saudi and Gulf Arab interests. [The Hill’s Kristina Wong]

IRAN NUCLEAR TALKS

Iranian President Hassan Rouhani said that Tehran was dealing with world powers, not the U.S. House or Senate, dismissing the compromise deal reached in the Senate on an Iran bill earlier this week. [Washington Post’s Karen De Young et al]

The political compromise on new Iran legislation—allowing Congress to weigh in on an emerging accord—could lead to harder negotiations with Iran, but is unlikely to be fatal to the diplomacy, reports Arshad Mohammed. [Reuters]
