U.S. President Donald Trump has said Mexican President Claudia Sheinbaum rejected his proposal to send U.S. troops to Mexico to help thwart the illegal drug trade because she is fearful of the country's powerful cartels.

The comments by Trump came a day after Sheinbaum confirmed that Trump pressed her in a call last month to accept a bigger role for the U.S. military in combating drug cartels in Mexico.

Iran's foreign minister held talks with top Pakistani officials on Monday to try and mediate in the escalation between Islamabad and New Delhi after last month's deadly attack on tourists in the Indian-controlled part of Kashmir.

Abbas Araghchi's visit to Islamabad was the first by a foreign dignitary since tensions flared in the wake of the April 22 massacre of 26 people — most of them Indian Hindu tourists — in the town of Pahalgam, which India blames on Pakistan. Tehran has offered to help ease tensions between the nuclear-armed neighbors.

Russian President Vladimir Putin has said that the need to use nuclear weapons in Ukraine had not arisen and that he hopes it will not.

Iran has unveiled a new solid-fuel ballistic missile with a range of 1,200 kilometers (745 miles), state television reported, at a time of rising tensions with the West.

"The solid propellant Ghassem Basir ballistic missile has a range of at least 1,200 kilometers and is Iran's latest defense achievement," the broadcaster said.

Iran defended on Saturday its "right" to enrich uranium despite growing Western concern that Tehran may be seeking nuclear weapons and as talks with the United States were delayed.

A Ukrainian drone attack left at least seven people dead and a Russian strike on Odesa killed two people Thursday, officials said, just hours after Kyiv and Washington signed a long-anticipated agreement granting U.S. access to Ukraine's mineral resources.

The attack in the partially occupied Kherson region of southern Ukraine, which struck a market in the town of Oleshky, killed seven and wounded more than 20 people, Moscow-appointed Gov. Vladimir Saldo said.

U.S. President Donald Trump said that he is nominating national security adviser Mike Waltz as United Nations ambassador while Secretary of State Marco Rubio would take over Waltz's duties on an interim role.

He announced the major shake-up of his national security team shortly after news broke that Waltz and his deputy are leaving the administration. Waltz has been under scrutiny for weeks after reporting from The Atlantic that he had mistakenly added the magazine's editor-in-chief to a Signal chat being used to discuss military plans.

The discussions have taken place in an ornate Kremlin hall, on the polished marble of St. Peter's Basilica and in a famously contentious session in the Oval Office of the White House.

What's emerged so far from the Washington-led effort to end the war in Ukraine suggests a deal that seems likely to be favorable to Russia: President Donald Trump has sharply rebuked Ukrainian President Volodymyr Zelenskyy, echoed Kremlin talking points, and indicated Kyiv would have to surrender territory and forego NATO membership. What's more, he has engaged in a rapprochement with Moscow that was unthinkable months ago.

The explosion that rocked an Iranian port, killing at least 70 people and injuring more than 1,000 others, had its epicenter at a facility ultimately owned by a charitable foundation overseen by Supreme Leader Ayatollah Ali Khamenei's office.

That foundation, known as Bonyad Mostazafan, faces American sanctions over it helping the 86-year-old Khamenei "to enrich his office, reward his political allies and persecute the regime's enemies," the U.S. Treasury has said. Its top personnel also have direct ties to Iran's paramilitary Revolutionary Guard, which oversees Tehran's ballistic missile arsenal and operations abroad targeting the Islamic Republic's enemies.

The United States said it expected new nuclear talks to take place soon with Iran but President Donald Trump vowed to enforce sanctions and called for global boycott of "any amount" of Iranian oil or petrochemicals.

Iran said that a fourth round of talks with the Trump administration, which had been set to take place this weekend in Rome, had been delayed.
