BUCHAREST, Sept 20 (Reuters) - The crew of a Togo-flagged general cargo ship bound for one of Ukraine's Danube river ports were evacuated early on Wednesday after an explosion on board near the Romanian port of Sulina, Romanian officials said. The Seama ship reported an explosion early on Wednesday and requested the evacuation of the 12-person crew near Sulina, where the Danube flows into the Black Sea. "At the moment the causes ... are unclear, whether it was a mine or merely an explosion in the engine room," Romanian Transport Minister Sorin Grindeanu told reporters. The crew were evacuated by the Romanian Agency for Saving Life at Sea (ARSVOM), which is coordinated by the transport ministry. Moscow has also been intensifying attacks on Ukraine's Danube river ports across from Romania since it abandoned a deal to lift a de facto Russian blockade of Ukraine's Black Sea ports.
