MOSCOW, July 23./ITAR-TASS/. Russia’s RT television channel has lost contact with its stringer Graham Phillips, a British subject, who is currently in Ukraine’s east, the RT press service told ITAR-TASS on Wednesday.

“We are trying to contact our stringer Graham Phillips but still without result,” the RT spokesperson said. “On Tuesday, July 22, he warned us about his plans to go to Donetsk’s airport, the site of armed clashes. We asked him to stay away as it was extremely dangerous. However, he went there with a group of other reporters, according to his posts on social networks.”

“At about 2 a.m. he texted ‘All is fine” from his mobile but since then the channel had no contact with Graham,” he said.

The RT stressed it that the channel had not tasked Graham to go the area of the airport.

“We are doing everything possible to locate his whereabouts,” the spokesman said adding that the channel “is employing all the resources.”

“We are keeping in touch both with DPR (the self-proclaimed Donetsk People’s Republic) and with Ukrainian representatives but still without success,” the RT said.

Phillips who is freelancing for RT was already detained in the south-eastern Ukrainian city of Mariupol by the country's National Guard in late May but later released.

After being detained, he was transferred to officers of the Ukrainian Security Service for questioning. In a telephone conversation with RT colleagues he said he had been asked whether he was a spy and what was his stance on Crimea.
