A U.S. federal judge blocks until June 20 the release in Syrian Democratic Forces-controlled territory of a dual-nationality Saudi-American citizen alleged to have joined ISIL. The man, who is now held for nine months in Iraq, was planned to be released by the U.S. military – with a new cell phone, some food and water and $4,210 in cash, but with no identification – as soon as tomorrow.
According to the United States Department of Defense, ISIL fighters killed a Navy SEAL near Erbil. The sailor was assisting Kurdish Peshmerga forces in repelling an attack on the area. The SEAL was later identified as Arizona native Charles Keating IV, the son of Charles Keating III, and the grandson of the convicted noted late financier Charles Keating Jr., who was embroiled in the 1980s savings and loan scandal.
During a visit to Baghdad, U.S. Defense Secretary Ash Carter announces that the United States will be sending more troops to the country to help in the fight against ISIL. The U.S. also plans to give Kurdish Peshmerga forces, which are fighting ISIL on the ground, more than $400m (£280m; €350m) in assistance.
The United States warns travelers in Italy that St. Peter's Basilica in Rome, the La Scala opera house in Milan, and the Milan Cathedral, as well as "general venues" like churches, synagogues, restaurants, theaters and hotels, have been identified as "potential targets" for terrorist attacks. The message added the Italian authorities are aware of these threats.
Kurdish forces, backed by U.S. airstrikes, capture several villages in an offensive to retake the Iraqi town of Sinjar from Islamic State militants, who overran it more than a year ago. The operation aims to cordon off the town, take control of Islamic State supply routes, and establish a buffer zone to protect the town from artillery, according to the Kurdish national security council.
