Russian President Vladimir Putin is stalling at the peace table while preparing a new military offensive in Ukraine, two senior U.S. senators warned Sunday, arguing that the next two weeks could shape the future of a war that has already smashed cities, displaced millions and redrawn Europe's security map.

Republican Sen. Lindsey Graham and Democratic Sen. Richard Blumenthal spoke to The Associated Press in Paris after meeting President Volodymyr Zelenskyy and touring neighborhoods shattered by what they called the worst Russian bombardments since the full-scale invasion began.

The United Kingdom will build new nuclear-powered attack submarines, get its army ready to fight a war in Europe and become "a battle-ready, armor-clad nation," Prime Minister Keir Starmer said Monday, part of a boost to military spending designed to send a message to Moscow — and Washington.

Starmer said Britain "cannot ignore the threat that Russia poses" as he pledged to undertake the most sweeping changes to Britain's defenses since the collapse of the Soviet Union more than three decades ago.

Most of the evacuated residents were from Manitoba, which declared a state of emergency last week. About 17,000 people there were evacuated by Saturday along with 1,300 in Alberta. About 8,000 people in Saskatchewan had been relocated as leaders there warned the number could climb.

Once a year, large numbers of Muslim pilgrims converging on Saudi Arabia unite in religious rituals and acts of worship as they perform the Hajj, one of the pillars of Islam. They fulfill a religious obligation, immersing themselves in what can be a spiritual experience of a lifetime for them and a chance to seek God's forgiveness and the erasure of past sins.

Here's a look at the pilgrimage and its significance to Muslims.

Saudi Arabia stopped more than 269,000 people without permits for the annual Hajj pilgrimage from entering Mecca, officials said Sunday, as authorities crack down on illegal journeys into the city.

The government blames overcrowding at the Hajj on unauthorized participants. It also says they made up large numbers of those who died in last year's searing summer heat.

Rafael Mariano Grossi, the director-general of the Vienna-based International Atomic Energy Agency, said that the agency compiled the report, because Iranian's uranium enrichment was an ongoing concern for the IAEA's board of governors.
