More than 25,000 residents in three provinces have been evacuated as dozens of wildfires remained active Sunday and diminished air quality in parts of Canada and the U.S., according to officials.

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.

Iranian, Egyptian and U.N. leaders met in Cairo on Monday to discuss Iran's nuclear program after a report from the U.N. nuclear watchdog agency said that Iran is further increasing its stockpile of uranium enriched to near weapons-grade levels.

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.

U.N. Secretary-General Antonio Guterres called on Monday for an independent investigation into the deaths of at least 31 Palestinians near a U.S.-backed aid distribution site in Gaza, after rescuers blamed the deaths on Israeli gunfire.

"I am appalled by the reports of Palestinians killed and injured while seeking aid in Gaza yesterday. It is unacceptable that Palestinians are risking their lives for food," Guterres said in a statement. "I call for an immediate and independent investigation into these events and for perpetrators to be held accountable."

Climate campaigner Greta Thunberg and other 11 activists set sail on Sunday afternoon for Gaza on a ship aimed at "breaking Israel's siege" of the devastated territory, organizers said.

The sailing boat Madleen, operated by activist group Freedom Flotilla Coalition, departed from the Sicilian port of Catania, in southern Italy.

Defense Minister Israel Katz vowed on Friday to build a "Jewish Israeli state" in the occupied West Bank, a day after the government announced the creation of 22 new settlements in the Palestinian territory.
