Turkish President Recep Tayyip Erdogan has signed into law a measure that would introduce a conditional pardon for thousands of Kurdish militants as part of a government peace effort with the Kurdistan Workers' Party, or PKK.

The measure was published in the Official Gazette on Tuesday. It will only come into force after Turkey's National Security Council confirms that the group has fully dissolved itself and disarmed.

Ukrainian forces staged one of their biggest drone attacks on Russia since Moscow's invasion more than four years ago, firing almost 800 drones just two days after launching a similar salvo, officials said Tuesday.

Meanwhile, a Russian missile strike on a village in Ukraine's northeastern Kharkiv region killed at least 10 people and wounded eight others as the barrage demolished homes, officials said Tuesday.

A hand grenade attack near a school in the Afghan capital Kabul on Monday afternoon wounded multiple children, authorities said.

Kabul police spokesman Khalid Zadran said late Monday that "a number of children" had been wounded, and said an investigation was underway. He did not provide further details.

South Korea's president said Tuesday a solid alliance with the U.S. strengthens the foundation of national security, as many South Koreans were baffled and concerned about U.S. President Donald Trump's abrupt order to "substantially reduce" joint military exercises.

Trump made the surprise announcement in a social media post just before U.S. and South Korean soldiers began Monday's annual Ulchi Freedom Shield exercises, which are largely designed to sharpen readiness against North Korean threats.

Japan's defense minister said Tuesday that cooperation between his country, the United States and South Korea was "critical", after U.S. President Donald Trump scaled back military drills with Seoul.

"As Japan faces the most severe and complicated security environment in the post-war era, the cooperation among Japan, the United States and South Korea is critical to the peace and stability of the region," Shinjiro Koizumi said in Australia after talks with his counterpart Richard Marles.

U.S. President Donald Trump on Monday threatened to bomb Oman if it "gets in the way" of a deal with Iran on the Strait of Hormuz and called for Iran to surrender.

"If Oman gets in the way, we'll bomb the shit out of them," Trump told Fox News journalist Trey Yingst, referring to ongoing talks between Oman and Iran on control of the strait, while Washington is also pursuing its own talks.

Russia attacked facilities of Ukraine's Naftogaz Group 13 times over the past week and has targeted its premises almost 300 times since the start of the year, the state energy company said Monday.

Russia has repeatedly battered the Ukrainian power grid since its all-out invasion more than four years ago. Moscow hopes to sap Ukraine's will to fight by denying civilians light, heating and running water during the bitter winter months.

South Korea on Monday expressed hopes for resumption of diplomacy between the U.S. and North Korea to ease animosities on the Korean Peninsula, hours after U.S. President Donald Trump said he ordered annual U.S. military exercises with South Korea to be scaled back.

Trump cited his good relationship with North Korean leader Kim Jong Un for the decision. The announcement baffled many in South Korea, a key U.S. ally in Asia where national security is a top priority due to threats from nuclear-armed North Korea.

The deal that U.S. President Donald Trump signed at Versailles in June set an ambitious 60-day deadline for ending the war with Iran and reaching an accord on its nuclear program.

The deadline was Monday, and the two sides are further apart than they were then.

The attacks began on a July weekend and have continued for a month, stretching from Moscow and St. Petersburg, to cities in the south, and eastward to the Ural Mountains. The targets weren't oil refineries, maritime hubs or arms plants hit by other Ukrainian strikes, but warehouses that bring the convenience of online shopping across the breadth of Russia.

Ukraine's drones have pummeled the giant depots belonging to Wildberries, Russia's biggest online retailer, burning billions of dollars' worth of merchandise and bringing the war home to the broad public.
