MOSCOW (AP) — Russia said Tuesday that a recent series of drone attacks on its military bases in Syria would have required assistance from a country possessing satellite navigation technology — a statement that appeared to be aimed at the United States. Russia's Defense Ministry said its forces repelled a series of drone attacks Saturday on the Hemeimeem air base and a naval facility in Tartus, adding that out of the 13 drones involved, seven were shot down and six were forced to land without inflicting any damage. Without blaming any specific country, the ministry said data for the attacks could only have been obtained "from one of the countries that possesses know-how in satellite navigation."
