A drone has struck a US-owned gas storage tanker at Egypt’s Mediterranean port of Damietta, according to maritime security firm Ambrey.

Two gas tankers caught fire at Damietta, port services firm Inchcape said.

The drone hit floating storage tanker Energos Winter, causing a fire ​that then spread ‌to another vessel, Gaslog Salem, three trading sources familiar with the ‌incident said. ​Two separate ⁠security sources said the cause of ⁠the blast ​was a drone strike.

The crew were evacuated ​and the fire ‌had been ​brought under control, Ambrey ​said, adding ⁠that ⁠no party had claimed responsibility.
