A Russian warship has entered the Mediterranean Sea and is headed toward the two United States Navy destroyers that launched an attack on a Syrian air base, according to a report from Fox News.

According to the report, the Russian ship came from the Black Sea and went through the Bosphorus Strait to reach the Mediterranean. There is no indication yet what the warship’s intentions are or if it is headed on a collision course with the two Navy destroyers.

The Fox report also claims that the Russian ship is “armed with advanced Kalibr cruise missiles.”

The report also notes that Russian news agency TASS claims that the frigate was headed on a routine trip toward a logistics base in Tartus, Syria, which is located 98 miles to the northwest of capital city Damascus.
