No group has claimed responsibility, but Yemen’s Iran-backed Huthi rebels have repeatedly targeted commercial vessels in the Red Sea and Gulf of Aden.
The Huthis, who control large parts of Yemen including the capital Sanaa, say their attacks are carried out in support of Palestinians during the war in Gaza.
Private security firm Ambrey said a Netherlands-flagged general cargo ship was reported to have come under attack, with “smoke in the vicinity of the vessel”.
The Huthis have also launched frequent missile and drone strikes on Israel, which has responded with air raids in Yemen.
Israeli strikes on Sanaa killed at least nine people on Thursday, a day after the rebels launched a drone attack on southern Israel.
