REUTERS/Umit BektasThe nearly month-long feud between Russia and Turkey reached a new battlefield over the weekend: the sea. A Russian warship fired warning shots at a Turkish fishing boat in the Aegean Sea, ostensibly to avoid a possible collision. The Russian Defense Ministry said the boat came within 1,600 feet of the Smetlivy destroyer, one of the ships bolstering the Kremlin’s military foray into Syria meant to prop up the regime of dictator Bashar al-Assad. Moscow summoned a Turkish military attaché over the incident, telling the official of “potentially disastrous consequences from Ankara’s reckless actions toward Russia’s military continent fighting against international terrorism in Syria,” the Defense Ministry said in a statement. “We are not in favor of tension," Turkey's Foreign Minister Mevlut Cavusoglu was quoted as saying in response.
