BBC News. I'm John Shea. A humanitarian ceasefire is due to come into effect between Armenia and Azerbaijan, whose forces have been fighting over the disputed territory of Nagorno Karabakh. The truce was agreed during talks in Moscow that stretched deep into the night. From Moscow, Sarah Rainsford reports. They were locked in talks for more than 10 hours, but the two sides have agreed to stop the fighting in Nagorno Karabakh. Russia's Foreign Minister Sergey Lavrov, who is mediating here in Moscow, said the ceasefire had been agreed for humanitarian reasons to recover the bodies of the dead and exchange prisoners, after two weeks of fierce clashes in which at least 400 people have been killed. It's not at all clear how long the ceasefire could hold beyond that, although Mr. Lavrov said Armenia and Azerbaijan had also agreed to return to substantive talks on a peace settlement for Nagorno Karabakh. Intense fighting has continued in the run-up to the truce. The pro-Armenian authorities in Nagorno Karabakh say Azerbaijan has struck civilian neighborhoods of the main city Stepanakert with missiles on Saturday. Earlier, Yerevan said Baku had intensified its drone strikes to try to alter the situation on the battlefield. But Azerbaijan says Armenia is intensively shelling populated areas near the breakaway territory.
President Trump says he stopped taking any medication against COVID-19 hours before he is due to hold an outdoor event with supporters at the White House. Speaking to Fox News, he also said he'd been retested for coronavirus, but had yet to receive the result. David Willis reports. The president conceded he could have contracted the virus at a White House event, such as the one held two weeks ago to introduce his latest nominee to the US supreme court, Amy Coney Barrett. With contract tracing from that occasion still underway, the president is nonetheless planning another such event this evening, having been cleared by his doctor to resume public engagements from today. Mr. Trump is also planning a campaign rally in Orlando on Monday. A swing state badly affected by the coronavirus, Florida, is about to welcome a president who at this stage has yet to be proven to no longer be contagious.
Hundreds of scientists from more than 40 countries have called for global action to protect whales, dolphins and porpoises from threats such as pollution and overfishing. Here's Helen Briggs. Save the whales was a familiar slogan decades ago, part of a movement that helped bring an end to commercial whaling. But while stricken populations had a chance to recover from organized hunting, then now facing other threats from human actions. The biggest danger is now accidental capture in fishing lines and nets. This kills an estimated 300000 whales, dolphins and porpoises a year. This is the latest world news from the BBC.
