YEMEN

Saudi-led coalition airstrikes hit al-Anad airbase in southern Yemen overnight and targeted areas around the port city of Aden, according to local officials and residents. [Reuters]

The U.S. is expediting weapons deliveries to the Saudi-led coalition in Yemen, and is also increasing intelligence sharing with the coalition, according to deputy Secretary of State Antony Blinken. [BBC]  The Obama administration’s decision to speed up the shipment indicates a “deepening involvement” in the offensive against the Houthi movement, report Kareem Fahim and Nick Cumming-Bruce. [New York Times]

Coalition forces, working with volunteer fighters loyal to President Hadi, have succeeded in forcing the withdrawal of Houthi fighters from areas in the south of the country, said the Saudi Defense Ministry spokesperson. [Asharq al-Awsat]

Pakistani parliamentarians argued against becoming involved in Yemen during a debate yesterday on a Saudi request to join the coalition. [Reuters] The parliamentary joint session to discuss involvement in Yemen has entered its third day. [Dawn]

Military advisers from Iran’s elite Revolutionary Guards are believed to be embedded in the Houthi rebel force which has taken control of large amounts of territory in Yemen, according to Saudi Arabia, with the country’s ambassador to the U.S. suggesting that Iran is providing substantial military support to the militia. [Wall Street Journal’s Jay Solomon] 

At least 560 people are thought to have been killed and 1,768 wounded, including many civilians, since fighting in Yemen intensified on March 19, according to the World Health Organization. And at least 74 children are thought to have been killed since the Saudi-led offensive began on March 26. [AP’s Ahmed Al-Haj]

IRAQ and SYRIA 

Two car bombs targeted two rebel bases to the north of Aleppo yesterday, killing and wounding dozens, according to two monitor groups. The compounds targeted belong to Islamic opposition groups and are strategically placed close to Turkey. [AP]

The next operation for Iraqi troops will be to retake Anbar province from the Islamic State, but how this can be accomplished is a “source of concern.” U.S. officials have expressed doubt over the involvement of Shi’ite militia forces in the operation into the Sunni-dominated area. [New York Times’ Rod Nordland]

U.S.-led airstrikes continue. Coalition forces conducted three airstrikes against Islamic State targets in Syria on April 6. Separately, coalition military forces carried out a further 12 strikes on targets in Iraq. [Central Command]

IRAN NUCLEAR DEAL

The nuclear framework is gaining broad support among Iran’s hardliners, including senior officials, lawmakers, clerics, and Revolutionary Guards commanders. [New York Times’ Thomas Erdbrink]

Basic elements of the agreement are “still in flux,” even as the White House steps up its lobbying efforts on the deal, report Michael R. Gordon and David E. Sanger. [New York Times]

Energy Secretary Ernest Moniz details previously unpublished terms of the agreement that make it more difficult for Iran to rebuild its nuclear weapons program, in an interview with Politico, reports Michael Crowley.

The White House “sales pitch [on an Iran deal] has only just begun,” press secretary Josh Earnest said on Tuesday, as the administration proposed classified briefings to sell the framework deal to key lawmakers. [The Hill’s Jordan Fabian] President Obama also held a private meeting with journalists to discuss the Iran talks earlier this week. [Politico’s Dylan Byers and Hadas Gold]

The “near-collapse” of the nuclear talks foreshadows the obstacles to securing a final accord with Iran, write Carol Morello and Karen DeYoung, who report on the “roller-coaster” talks that led to the framework deal. [Washington Post]

Henry Kissinger and George P. Shultz explore the consequences of an Iran deal. The “ultimate significance” of the accord will be contingent upon “its verifiability and enforceability,” write the former secretaries of state in a Wall Street Journal op-ed. Meanwhile, over 50 foreign policy luminaries have signed a statement welcoming the progress made in the negotiations and calling on lawmakers to hold off on any legislative action on Iran. [The Hill’s Kristina Wong]

Israel’s latest demands are “unrealistic,” according to the New York Times editorial board, and could “scuttle what seems to be a very serious and potentially groundbreaking deal.” Daniel W. Drezner explains why Israeli Prime Minister Benjamin Netanyahu is “the least important player on the Iran chessboard.” [Washington Post]
