MOSCOW (AP) — Russia’s foreign minister lashed out at Britain on Thursday for pressuring a Russian-operated ship heading to Syria with a load of weapons to turn back, saying that Moscow won’t abide by European Union sanctions against its Arab ally.

Sergey Lavrov said a British insurer’s decision to remove the ship’s coverage reflected the “unreliability of the British insurance system.” He also said the British government defied international law by asking the insurance company to act.
