His response to comments by the Deputy Chair of Russia's Security Council, who's calling Trump's demands to stop bombing Ukraine by next Friday an ultimatum. Julia Chapman explains. Dmitry Medvedev is known for making inflammatory statements, but he wields little power in Russia. Nevertheless, Donald Trump said words can often lead to unintended consequences.

A threat was made and we didn't think it was appropriate. Medvedev's comments followed an ultimatum issued by the U.S. president. He demanded that Russia end the war in Ukraine by August 8th. Last month he also threatened tariffs on the country's energy exports. Leslie Vingimori is president of the Chicago Council on Global Affairs. You know it's a sort of thing that when you send nuclear submarines, you normally do it under a veil of secrecy. The Kremlin hasn't commented on America's submarine deployment.

But Friday, President Vladimir Putin suggested Trump's deadline wouldn't make him change course. The Russian leader said the army is continuing to advance. Donald Trump described Russia's actions as disgusting. Julia Chapman, CBC News, London. Canadian swimmer Summer Macintosh was vying for a fourth consecutive gold medal at the World Aquatics Championships in Singapore this morning. Unbeaten in this event and she's going to remain unbeaten because Katie Ledecky has sprinted clear.

What an effort responding to the challenge and Ledecky wins the gold again. But American Katie Ledecky the current world record holder held on to win the women's 800 meter freestyle. McIntosh, the 18 year old Toronto native placed third earning a bronze behind Ledecky and Australian Lanny Palaster. That was not the race I wanted. It was personally my time, how I executed anything. But it is a new event for me. I gave it 10% more focus than I have in the past, so it's just the beginning and I know

I have lots of time in my career to do better at it. McIntosh has now won three gold medals and a bronze so far. She'll try to make it four gold medals tomorrow when she competes in the 400 meter individual medley. Well, it's been a summer of wildfires in Portugal. One in particular, the Ponta da Barca, has officials on edge watching to see if winds whip up the flames after days of crews working to bring it under control.

Alison Roberts reports from Lisbon. A week after it was reported, a fire in the hills near Pont da Barca in Portugal's far north is still burning with hundreds of firefighters on the ground. Residents of four villages have already had to flee their homes. In this and other cases arson is suspected and at least one individual has been detained but conditions are also ripe for fires to spread. The vast majority of land holdings in the north and center of Portugal are

small and few are professionally managed to reduce fire risk and in the last couple of weeks there's been a sharp rise in daytime temperatures and just as importantly in overnight lows. Temperatures are seen climbing further today and Sunday to as high as 40 degrees in the capital, Lisbon, and 42 in the interior. Alison Roberts for CBC News, Lisbon. And now coming into view is Zina Cardman, again her first time on board the International Space Station as well. An international crew of astronauts is welcomed onto the International Space Station.

The crew includes two NASA astronauts, a Russian cosmonaut and a Japanese astronaut. They took off on a SpaceX rocket early this morning for the mission, which NASA is calling Routine. The mission, dubbed Crew-11, is expected to last eight months. That's up from the usual six months time. NASA says it intends to better align the mission schedules of the U.S. and Russia. And that is your World This Hour. For CBC News, I'm Claude Fague.
