Armed assailants abducted four crew members from a tanker in a piracy incident off Togo in West Africa's second hostage incident in three days.

The attack occurred in the early morning hours of 4 November on the 94,100-dwt Elka Aristotle (built 2003), Greek coastguards said on Monday.

Four members of the vessel’s crew of 24 people on board were kidnapped: two Filipinos, one Greek and one Georgian.
