The Pentagon says a Russian fighter plane flew within about 10ft (3m) of one of its reconnaissance aircraft operating over the Black Sea.

US officials described the intercept by the SU-27 jet on Wednesday as "dangerous and unprofessional".

Russia's defence ministry said the US plane had been approaching Russian territory and the SU-27 pilots had adhered to international rules.

Russia is currently carrying out military exercises in the Black Sea.
