Answer: Iran
Notes: The largest warship in the Navy of Iran has recently caught fire and later sank in the Gulf of Oman, according to the media reports. The support warship Kharg was named after the island that serves as the main oil terminal for Iran. Though the firefighters tried to contain the blaze, the vessel sank near the Iranian port of Jask, southeast of Tehran on the Gulf of Oman. It is near the Strait of Hormuz, the narrow mouth of the Persian Gulf.
