Britain's marine security agency on Saturday reported a small explosion near a vessel 170 nautical miles east of Yemen's Aden, an area where Houthi militants have been targeting commercial ships in solidarity with Palestinians, APA reports citing Reuters.
UKMTO initially said the incident happened southwest of Aden.
"An armed security team observed a small explosion near the vessel," the UKMTO advisory said, quoting the master of the MV Groton, who said there was no damage and all crew members were safe.
