The two tankers, the Virat and the Kairos, were rocked by explosions in Turkey’s coast late Friday, according to the Turkish transport ministry.
One of the two was struck again early Saturday, the ministry added.
“Modernised Sea Baby naval drones successfully targeted the vessels,” a source in Ukraine’s SBU security service told AFP.
It shared a video that purported to show sea drones gliding towards the two ships, before sparking explosions.
