Who will Putin blame for the terror attack?
From our UK edition
A branch of the Islamic State terror group, Isis-K, has claimed responsibility for last night's stadium terror attack in Moscow. US officials, who had warned of such an attack two weeks ago have said this sounded credible. But the Kremlin has not accepted the Isis-K claim and says it’s looking at all explanations – even (as some Russian journalists are advocating) that the attack was organised by the Ukrainians. Putin himself has hinted at this, saying the FSB had apprehended men on their way to the Ukrainian border. As I reported last night, western intelligence warned the Kremlin of a likely terrorist attack on Russian soil earlier this month.
