America has warned Iraqi officials not to move troops from the front lines against ISIS to protect Baghdad, as already about 50% of Iraq’s active forces are focused on securing the capital – a proportion considered sufficient by American military advisers, said Col Steve Warren, spokesman for the US-led coalition against Islamic State.

SOUTH CHINA SEA

A US military plane was intercepted in an “unsafe” manner by two Chinese fighter jets over the South China Sea, the Pentagon said yesterday. Beijing’s response was that America must end surveillance near China. [Reuters’ Idrees Ali and Megha Rajagopalan]  If a final US investigation concludes that the interception was definitively unsafe, “it would mark the first such dangerous midair encounter between US and Chinese aircraft” over that body of water since 2014.

China’s Foreign Minister Wang Yi has accused the US of militarizing the South China Sea, rejecting American claims to the contrary, during an interview with Al Jazeera.

CYBERSECURITY, PRIVACY and TECHNOLOGY

Google’s new messaging service, “Allo,” will offer end-to-end encryption, the tech giant announced yesterday.

There were 66 people on board.  Earlier, the former president of the French air accident investigation bureau told journalists that “there’s a strong possibility of an explosion on board from a bomb or a suicide bomber.” Investigators are focusing their attention on ground crew at Paris’ Charles de Gaulle airport in an attempt to establish whether any airport employees posed a security risk. This story continues to unfold.  Live updates are being provided by the Guardian and the BBC.

Saudi-Israeli relations are flourishing under a “shared sense of betrayal and abandonment” by a Washington focused on Iran, writes Todd Rosenblum.

[Politico]

“Our behavior, as an organization and as individuals, must signal our commitment to the values we so often proclaim.” Adm.
