Russia Sending Spy Ship To Mediterranean
Russia is sending a reconnaissance ship to the eastern Mediterranean as the United States prepares for a possible military strike in Syria, Interfax news agency reported on Monday.
US President Barack Obama has said he will seek congressional authorization for action against Syria after what Washington said was a sarin gas attack that killed over 1,400 people.
The reconnaissance ship left Russia’s naval base in the Ukrainian Black Sea port of Sevastopol late on Sunday on a mission “to gather current information in the area of the escalating conflict”, the Interfax report quoted an unidentified military source as saying.
The Defense Ministry declined immediate comment but Interfax said the vessel, the SSV-201 Priazovye, would operate separately from a Russian navy unit already stationed in the Mediterranean.
Last week, the ministry said new warships were being sent to the Mediterranean but described this as a routine rotation of ships under a permanent deployment which Moscow says is needed to protect national security interests.
Foreign Minister Sergei Lavrov also said at the time that Moscow did not intend to be dragged into any military conflict over Syria.
Russia reiterated on Monday that the United States had not proved its allegations and that the chemical attack may have been staged by Syrian rebels to provoke outside intervention in the more than two-year-old civil war.
