Biggest ship in Iran's navy catches fire and sinks under unclear circumstances, semiofficial Iranian news agencies say

Tehran, Iran — The largest warship in the Iranian navy caught fire and later sank Wednesday in the Gulf of Oman under unclear circumstances, semiofficial news agencies reported.

The Fars and Tasnim news agencies said efforts failed to save the 679-foot support ship Kharg, named after the island that serves as the main oil terminal for Iran. The Reuters news agency reported that the entire crew was able to safely disembark. Reuters cited Fars, which quoted a navy statement. The statement said the Kharg was on a training mission.
