Iran frees US sailors held in Gulf

Iran's Revolutionary Guards have released 10 US sailors held for entering its territorial waters in the Gulf, state television reported.

They were detained on Tuesday after one of their two vessels broke down during a training mission, the US says.

News of the sailors' release came shortly after the guards said the US had apologised for the incident.

It comes at a sensitive time, as the US and Iran try to implement the deal on Iran's nuclear activities.
