TEHRAN - The Iranian Navy's Alborz destroyer entered the Red Sea on Monday after passing through the Bab el-Mandeb Strait amid rising tensions in the region, the semi-official Tasnim news agency reported.

The Alborz destroyer was part of the Iranian Navy's 94th flotilla of warships, said the report, adding that the Iranian Navy's flotillas have been conducting missions on the high seas since 2009 to ensure shipping security and fight piracy.
