The Russian Foreign Ministry in late September urged the countries of the region to consolidate their efforts to combat piracy after two Russian nationals were captured by pirates during an attack on the Water Phoenix cargo ship on 8 September.
The two hostages were later released on 31 October, Russian Foreign Ministry spokeswoman Maria Zakharova announced in early November.
