Commercial ships face increasing dangers at sea after armed groups have attacked and seized vessels in waters around the Red Sea and off the coast of Yemen, adding to perils for seafarers, shipping officials said on Wednesday.

An attempted hijacking of a commercial vessel in the Gulf of Aden on Sunday appears to have been carried out by armed Somali pirates and not Yemeni Houthis, despite the firing of missiles from Houthi-controlled territory in Yemen afterward, the Pentagon said on Monday.

The incident is the latest in a series of attacks in Middle Eastern waters since a brutal war between Israel and the Palestinian Islamist group Hamas broke out on Oct. 7.
