A fire swept through a building in a New Delhi neighborhood Wednesday, killing at least 21 people and injuring several others, police said.

The building in the Malviya Nagar neighborhood in the southern part of the city had a restaurant on the ground floor and a hotel above. The predominantly residential area is densely populated and is popular with students and young professionals.

Ukrainian long-range drones struck an oil terminal in St. Petersburg and set it ablaze, Ukrainian President Volodymyr Zelenskyy said Wednesday, as the Russian city hosted an annual international economic forum promoted by President Vladimir Putin.

The drones flew more than 1,000 kilometers (600 miles) to hit the terminal, Zelenskyy said on social media. Clouds of black smoke rose over the city's port after the attack.

Secretary of State Marco Rubio on Tuesday expressed hope that a deal to end the war in Iran was in the cards, stressing that Tehran must severely curtail its nuclear program before any sanctions are lifted.

Russia launched hundreds of drones and dozens of missiles against Kyiv and other Ukrainian cities overnight, killing at least 14 civilians and wounding more than 100 others, authorities said Tuesday.

Some people were trapped under the rubble of apartment buildings, including a 3-year-old child whose body was pulled out by emergency crews in the central Ukrainian city of Dnipro, officials said, as the attack stretched from night into day and the boom of explosions reverberated across cities.

U.S. President Donald Trump said Monday that talks with Iran were moving ahead rapidly, despite Iran's Tasnim news agency reporting Tehran had halted talks in protest at Israel's Lebnanon offensive.

"Talks are continuing, at a rapid pace, with the Islamic Republic of Iran. Thank you for your attention to this matter!" Trump said on his Truth Social account, shortly after another post saying Israel and Hezbollah had agreed to stop attacks.

Iran's Tasnim news agency said Tehran was suspending all exchanges with mediators in peace talks with the United States on Monday, blaming Israel's ongoing invasion of Lebanon.

"Given the continuing crimes of the Zionist regime (Israel) in Lebanon and considering that Lebanon was one of the preconditions for the ceasefire and that this ceasefire has now been violated on all fronts, including Lebanon, the Iranian negotiating team is suspending dialogues and exchange of texts through mediators," Tasnim reported.

Iran's chief negotiator warned the United States is not to be trusted Sunday, saying Tehran would not agree to any deal with Washington unless it fully secures Iranian rights.

U.S. President Donald Trump said he had secured guarantees from Iran that it would not develop nuclear weapons, as reports emerged he had sent a tougher peace proposal back to Tehran.

Any tweaks to the proposal could prolong even further an agreement to formally end the Middle East war and open the Strait of Hormuz maritime route after weeks of efforts to secure a deal despite fractious rhetoric and the occasional flare up of armed conflict.

Russia said Saturday it had recalled its ambassador to Armenia for "consultations" over Yerevan's growing ties with the EU, a day after President Vladimir Putin warned the Caucasus country against pivoting to Brussels.

The United States warned on Saturday it was "more than capable" of resuming war with Iran after President Donald Trump said any peace deal must adhere to his red lines, including Tehran never being able to develop nuclear weapons.
