Another ship has reportedly been hijacked by pirates off Somalia's coast

Pirates have hijacked another vessel off Somalia's coast — the second in recent weeks — stoking fears that piracy could be returning to the African Horn nation's waters.

The agency did not offer any details on who the hijackers were but said an investigation is underway.

The European Union's Naval Force reported that a Maltese-flagged merchant vessel was hijacked in the nearby Arabian Sea last week and moved to the same area off Somalia's coast. The bulk carrier Ruen had 18 crew onboard when it was hijacked near the Yemeni island of Socotra, around 150 miles off Somalia.
