Three journalists, including a Briton, have been detained in Ukraine.
The British Foreign Office confirmed freelance reporter, Graham Phillips, from the Russian TV channel Russia Today, was stopped by Ukrainian authorities in the east of the country.
The detention follows the earlier arrests of two Russian journalists near Slovyansk on Sunday after they were accused of taking part in an operation with separatists to attack a military airfield.
Earlier, Ukrainian authorities released a video in which the men were alleged to have been found with a rocket launcher.
Moscow has demanded the duo’s immediate release with President Vladimir Putin describing the claim that they were involved in a terrorist plot as ‘nonsense’.
