Russia and US sign deal to avoid air clashes over Syria
US and Russian officials said Tuesday their governments had signed a deal they hope will avert clashes between their air forces in the skies over Syria, a week after Russian and US combat aircraft found themselves 15-30km apart. Pentagon spokesman Peter Cook said the text of the deal would remain secret at Moscow's request, but that it laid out means for both sides to communicate and establish a hotline on the ground. The two countries would not, however, share intelligence on their targets, he said.
