Ukraine and Russia accused each other of launching attack drones on one another overnight, hours after Russian President Vladimir Putin spoke by phone with his US counterpart Donald Trump - and again refused an immediate ceasefire.

At least 17 people died when a fire broke out due to a short circuit in a building in the Indian city of Hyderabad on Sunday, officials said.

Putin added that Russia’s main objective was “to eliminate the root causes of this crisis”, in language that signalled that his key demands remain unchanged.

Russia banned Amnesty International on Monday by classing it as an "undesirable organisation" for backing Ukraine against Russia, drawing a rebuke from the group which said it would redouble efforts to expose Russian human rights abuses.

The designation mandates penalties of up to five years in prison for Russian citizens working with or funding designated groups.
