An “unlikely alliance” has formed between an Arab tribal force and a leftist Kurdish group in northern Iraq, a “measure of the extent to which Islamic State has upended the regional order.” [Reuters’ Isabel Coles]

“But the danger is that this will become a simplistic, mob-rule pursuit of Blair himself.” Jackie Ashley argues for why the Chilcot report on the Iraq war should not be used to blame the UK’s involvement in Iraq on “one man” – former prime minister Tony Blair. [The Guardian]

GUANTANAMO BAY

Classified information was accidentally revealed during a Guantánamo Bay military commission hearing for the 9/11 defendants in February, which later appeared on computers used by defense lawyers, prosecutors, and the judge, according to a court filing that has recently been released. [Politico’s Josh Gerstein]

The judge who imposed a no-touch order on female guards at Guantánamo Bay has said that he will expedite the lifting of the order if the Pentagon takes “appropriate action to absolve any taint” caused by Secretary of Defense Ash Carter and Marine Gen. Joseph Dunford Jr.’s previous criticism of the order, though he has not specified what the officials must do. [Miami Herald’s Carol Rosenberg]

CYBERSECURITY, PRIVACY and TECHNOLOGY

Cybersecurity, privacy and national security experts were summoned to appear before the Senate Judiciary Committee yesterday to explain the possible implications of reauthorizing a law which the NSA says allows it to gather online communications from sites such as Facebook and Google. The NSA uses programs PRISM and Upstream, which are aimed at “foreign targets” but also dredge up “a potentially vast” amount of non-public data involving innocent US citizens.

YEMEN

The ceasefire in Yemen is being threatened by a steep escalation in violence over the past few days, but even if the government-Houthi negotiations succeed, Yemenis say the “vicious fighting, past broken promises and deepening divisions” may lead them into another, even uglier war, reports Kareem Fahim. [New York Times]

The identity of an al-Qaeda bomb-making instructor has been revealed: Anwar al-Awlaki, the US imam who joined the Islamist group in Yemen and became its leading English-speaking propagandist.

The revelations were made in court documents relating to the case of Minh Quang Pham, a British al-Qaeda operative currently on trial. [New York Times’ Scott Shane and Benjamin Weiser]

EUROPEAN TERROR THREAT

Cheryl Mills served as chief of staff while Clinton was secretary of state. [Washington Post]

OTHER DEVELOPMENTS

Obama will become the first US president to visit Hiroshima when he makes a “historically symbolic” visit at the end of this month. The trip could signal a transformation in US-Japan relations, or it could “open old wounds” dating back to the US’ detonation of a nuclear bomb there at the close of WWII, which killed over 100,000 people. Both Japan and the US are keen to avoid the impression that the visit is an apology for the bombing, report Gardiner Harris et al. [New York Times]

The visit will provide Obama with a major opportunity to put forward “some tangible new initiatives to advance his vision of a nuclear-free world,” write the New York Times editorial board, as well as a chance to “improve his credibility” on this issue, which has been marred by such moves as his support for a $1 trillion progam to rebuild the US nuclear arsenal over the next 30 years.

The most detailed information yet about how Islamic State recruited almost a dozen men from Minneapolis around two years ago is expected to be revealed during the trial of three Somali-Americans, part of a group accused of plotting to join the Islamist organization. Six others have already pleaded guilty. [NPR’s Dina Temple-Raston]

“We must be careful not to fall into the trap of putting in place policies and procedures that normalize and legitimize extrajudicial killing,” argues Chris Cole following yesterday’s publication by the UK Parliament’s joint committee on human rights of a report on the use of armed drones for targeted killing, and its Chair’s suggestion that an independent body be set up to which military force which takes place outside of conventional armed conflict can be referred. [The Guardian]

The likely appointment of Rodrigo “the Punisher” Duterte as the Philippines’ next president may have “a major impact” on the deadlock in the South China Sea, writes Emily Rauhala. Very little is known about Duterte’s policy on China. [Washington Post]

Five Australians have been arrested for allegedly planning to join Islamic State by sailing a small boat to Indonesia and the Philippines before making their way to Syria, Australian officials have said. [BBC; Reuters’ Matt Siegel]
