A new ballistic missile fired by Russia at the Ukrainian city of Dnipro last week carried multiple warheads but no explosives, and caused limited damage, two senior Ukrainian government sources said.

Russia has dubbed the missile the Oreshnik (Hazel Tree) and said it is impossible to intercept it with air defences. Ukraine has said the weapon reached a top speed of more than 13,000 kph (8,000 mph) on its way towards Dnipro on Thursday. Intermediate-range ballistic missiles have a range of up to 5,500 kilometres.
