Ukrainian president condemns attack on the eastern city of Kostiantynivka, where a child was among the dead

Cuba has uncovered a human trafficking ring aimed at recruiting Cubans to fight as mercenaries for Russia in its war in Ukraine, its foreign ministry has said, as Moscow seeks to increase the size of its forces.

In a statement, the Cuban foreign ministry said the authorities were working to “neutralise and dismantle” the network, which it said was operating within the Caribbean island nation and in Russia.
