The Brief

Ukraine fired more than 1,000 drones at Russia overnight, including hundreds aimed at Moscow, in what the city's mayor called the largest-ever attack on the Russian capital. Officials said the strikes damaged a Moscow oil refinery and a residential building.

Russia said it intercepted about 450 of the drones headed for Moscow and that across the wider Moscow region, the attack killed two people and wounded 20, a local official said. The mayor said Russia has intercepted 1,600 drones in total since Saturday.

Saudi Arabia said Yemen's Houthi rebels attempted to strike Riyadh with a ballistic missile, the first time the Saudi capital has been targeted since fighting between the Houthis and Saudi Arabia escalated. The Saudi-led coalition said its air defenses intercepted the missile, and a reported strike near the airport's fuel depot caused delays.

The Houthis have since warned against Saudi Arabia joining Yemen's growing civil war. A Houthi political bureau member said Washington had reached out to the rebels after their rapid advance down Yemen's western coast to the Bab el-Mandeb Strait earlier this month.

The United States and Denmark reached an agreement after months of threats from President Trump to annex Greenland. Trump said the deal gives the US "permanent security control" over the territory, addressing US security concerns.

Danish and Greenlandic leaders reacted cautiously, expressing optimism after officials from the US, Denmark and Greenland negotiated quietly for months. NATO welcomed the agreement.

Exit polls showed damaging losses for Chancellor Friedrich Merz's center-right CDU in state elections in Berlin and Mecklenburg-Vorpommern, with the far-right Alternative for Germany party making significant gains. In Mecklenburg-Western Pomerania, the CDU's result was reported at just 5%, the party's lowest ever in any state since World War Two.

Merz called the results a "disaster" for his party but said he would stay on and press ahead with his government's reform agenda.

Treasury Secretary Scott Bessent met with Chinese Vice Premier He Lifeng in New York on Sunday, opening high-level talks ahead of a planned summit between President Trump and Chinese President Xi Jinping later this week.

Xi is expected to travel to the White House for the summit, one of the most closely watched moments in the two countries' relations in recent months.

Polls closed in Russia's first parliamentary election held during the war in Ukraine, with the ruling United Russia party set to dominate the results. President Vladimir Putin cast the vote as a test of public support for the war.

The vote included residents of four Ukrainian regions that Moscow illegally annexed after the war began but does not fully control, as well as Crimea, which Russia illegally annexed in 2014.
