A vessel that was seized in the Gulf of Aden has been moved into Somali territorial waters, according to the UK Maritime Trade Operations (UKMTO). The agency, which monitors maritime security, reported the seizure late Tuesday and has now classified the incident as a hijacking. The Gulf of Aden, located off the coast of Yemen, is a critical shipping route connecting the Red Sea to the Indian Ocean. The area has seen periodic piracy attacks, though incidents have declined in recent years due to international naval patrols. The UKMTO did not provide details about the vessel's nationality, crew, or cargo. It urged vessels in the region to exercise caution. The hijacking comes amid ongoing instability in Yemen and Somalia, which have struggled with piracy and maritime security threats. Authorities are investigating the incident. No group has claimed responsibility so far.
