A NATO F-16 fighter jet buzzed a plane carrying Russian Defence Minister Sergei Shoigu as it flew over the Baltic Sea, but was seen off by a Russian Sukhoi-27 military jet, Russia said on Wednesday, an account partly disputed by NATO.

The older brother of a Syrian boy whose image, dazed and bloodied after an air strike, shocked people around the world, has died in Aleppo from wounds sustained in the same incident.

Under U.S. military rules of engagement, the Navy ship that Russian military jets buzzed in the Baltic Sea this week could have opened fire, Secretary of State John Kerry said Thursday.
