MOSCOW, July 21. /TASS/. Diplomats continue efforts to contact the Russian crew members of the Stena Impero oil tanker, a spokesperson for the Russian embassy in Tehran told TASS on Sunday.

"We managed to contact the head of the Iranian Foreign Ministry’s office in the city where the tanker had been taken," he said. "According to him, the crew members remain onboard and are free to move about the tanker. At the same time, international maritime rules prevent them from leaving the vessel," the spokesperson added.

"The crew members are well, there are no threats to their life and health," the Russian diplomat said, noting that "we are working with our Iranian partners, seeking to contact the Russian sailors."
