Ukraine and Russia have agreed to a ceasefire deal involving the Black Sea and strikes on energy infrastructure.
It comes after US officials met separately with a Russian and Ukrainian delegation in Riyadh, Saudi Arabia, to discuss a partial ceasefire as Moscow's full-scale invasion has been raging on for more than three years.
Ukraine and Russia didn't directly meet, and agreed to the US-formed plan.
Discussions on Monday were focused on a narrow Black Sea ceasefire between Ukraine and Russia, but US President Donald Trump said territory and power plant ownership were also on the agenda.
