Shipowners have been warned of a growing threat of piracy in the Gulf of Guinea following two attacks on Monday, including a reported kidnapping.

Piracy reporting body MDAT-GoG has said there is a heightened risk for vessels after a containership raid was thwarted at the southern edge of the Nigerian exclusive economic zone (EEZ).

Maritime security company Dryad Global named the vessel as Mediterranean Shipping Co (MSC)'s 1,893-teu MSC Lucia (built 1985).
