This and the minority emergency of Christians and Yazidis have at last prompted more vigorous responses today:
1) Emergency session of the United Nations Security Council, probably with specific measures. The session will be held at 11:30 p.m. GMT (7:30 p.m. local time). Please contact United Nations Missions of Security Council permanent members - by mail or Twitter: @USUN, @RussiaUN, @UKUN_NewYork, @franceonu
2) The United States is considering specific measures, including airstrikes, that could begin at any moment.
3) France will send military aid to the forces fighting for the Kurdish Region (mostly Kurds, but also many Assyrians are in the Kurdish troops and their allies).
[Update: 9:00 p.m. GMT:] From the Times (UK): "US carrier is set for attack - The USS George HW Bush, equipped with four squadrons of F/A-18 Super Hornet jet fighters, is waiting for an order from President Obama to launch strikes against the Islamic State"
[Last update: 11:20 p.m. GMT:] As in Aesop's fable, the mountain in labor gave birth to a mouse... From the U.N. Security Council, a third innocuous "condemnation" of the terrorists, and "support" for the Iraqi government. From the US government so far, not any intervention regarding ISIS, but only humanitarian aid to some isolated groups, dropped without even certainty that it will help them or be seized by the attackers, as it often happens in such circumstances.
