Don't believe the name: The Demilitarized Zone between the two rival Koreas might be the most heavily armed place on earth. Two million mines, barbed wire fences, tank traps and tens of thousands of troops from both countries patrol a divided swath of land 248 kilometers (154 miles) long and 4 kilometers (2.5 miles) wide.

So how, on the eve of Russian President Vladimir Putin's summit Wednesday with North Korean leader Kim Jong Un, did as many as 30 North Korean soldiers wander over the line separating North from South, causing South Korea to fire warning shots before the North Koreans withdrew?

The Sudanese government has accused the United Arab Emirates of fueling the 14-month war in the African country by providing weapons to a rival paramilitary force. The UAE dismissed the allegation as "ludicrous," calling "a shameful abuse by one of the warring parties."

The clash came during a U.N. Security Council meeting at which Assistant Secretary-General Martha Pobee warned that atrocities are being committed along ethnic lines in Sudan's western Darfur region.

Russian President Vladimir Putin and North Korean leader Kim Jong Un signed a new partnership that includes a vow of mutual aid if either country is attacked, during a Wednesday summit that came as both face escalating standoffs with the West.

The deal, which the leaders said covered areas including security, trade, investment, and cultural and humanitarian ties, could mark the strongest connection between Moscow and Pyongyang since the Soviet Union collapsed in 1991. Both leaders described it as a major upgrade of their ties.

One of Donald Trump's emissaries to Arab Americans is a Lebanese-born businessman who moved to Texas as a teenager, speaks Arabic, English and French, and recently joined the Trump family when his son married the former president's younger daughter.

Massad Boulos has taken on the challenge of trying to convince a politically influential community angry at President Joe Biden that Trump is a better option. But many Arab Americans also note Trump has positioned himself as more pro-Israel than Biden and has made a series of comments and policy announcements that critics blast as Islamophobic.

World leaders have backed Ukraine's independence and territorial integrity, and the need for eventual talks with Russia on ending the war -- but left the key questions of how and when unresolved.

More than two years after Russia invaded, leaders and top officials from more than 90 states spent the weekend at a Swiss mountainside resort for a two-day summit dedicated to resolving the largest European conflict since World War II.

The international Ukraine peace summit was to focus Sunday on food security, avoiding a nuclear disaster and returning deported children from Russia as countries outlined building blocks towards ending the war.

More than two years after Russia invaded, leaders and top officials from more than 90 states were spending the weekend at a Swiss mountainside resort for a landmark two-day summit dedicated to resolving the largest European conflict since World War II.

World leaders headed to Switzerland on Saturday for a first summit on peace in Ukraine, after Vladimir Putin demanded Kyiv effectively surrender if it ultimately wants negotiations with Moscow.

Iran has started up new cascades of advanced centrifuges and plans to install others in the coming weeks after facing criticism over its nuclear program, the United Nations' atomic watchdog said Friday. The U.S. called the moves "nuclear escalations."

Spinning up new centrifuges further advances Iran's nuclear program, which already enriches uranium at near-weapons-grade levels and boasts a stockpile enough for several nuclear bombs if it chose to pursue them. However, the acknowledgement from the International Atomic Energy Agency did not include any suggestion Iran planned to go to higher enrichment levels amid wider tensions between Tehran and the West as the Israel-Hamas war rages in the Gaza Strip.

Russian President Vladimir Putin on Friday said Moscow would cease fire and begin peace talks "immediately" if Ukraine pulled back troops from four regions and gave up its NATO membership bid.

"As soon as Kyiv says it is ready to do this and begins really withdrawing troops and officially renounces plans to join NATO, we will immediately, literally that very minute, cease fire and begin talks," Putin said at a meeting with Russian diplomats in Moscow.

Switzerland will host scores of world leaders this weekend to try to map out first steps toward peace in Ukraine even though Russia, which launched and is continuing the war, won't take part.

Ukrainian President Volodymyr Zelenskyy's government didn't want Russia involved, and the Swiss — aware of Moscow's reservations about the talks — didn't invite Russia. The Swiss insist Russia must be involved at some point, and hope it will join the process one day.
