The Ukrainian president says he will see his US counterpart in Florida, as Kyiv's mayor says Russia launched new air strikes on the capital.

Police say the attacker, from the occupied West Bank, ran over at least one person before stabbing another victim several miles away.

President Trump has previously accused the Nigerian government of failing to protect Christians from jihadists.

The decision has been condemned by Somalia, Egypt, Turkey and Djibouti, who call it a dangerous precedent.
