Russian diplomat: "We have plans against NATO."

The attack caused fires at a large electronics plant in Mukachevo, with damage also reported in other cities, including Lviv.

"We are ready for the bilateral meeting. If the Russians are not, then we would like to see a strong response from the United States," Zelensky said, adding that he asked Trump to impose additional sanctions on Moscow if it rejects talks with Ukraine.

Ukraine’s military intelligence (HUR) struck a Russian patrol boat in the Black Sea near the occupied town of Zaliznyi Port in Kherson Oblast, killing five crew members, HUR reported on Aug. 21.

The number includes 830 casualties that Russian forces suffered over the past day.

"There’s the dawning reality that this will be Europe making this happen on the ground... The U.S. is not fully committed to anything," an unnamed NATO diplomat said.

The attack allegedly hit the Novoshakhtinsk oil refinery, which has previously been targeted in Ukrainian drone strikes.

The plan would require countries that have signed security agreements with Ukraine to deliberate and respond quickly in the event of another Russian attack following a peace agreement. It would not include NATO membership for Ukraine.

Ukraine's Crimean peninsula, illegally occupied by Russia since 2014, is roughly 26 times smaller than Texas.

Closer to Ukraine, Lithuania said it was ready to put troops on the ground as part of a peacekeeping force, while Poland said its soldiers would assist the "coalition of the willing" from Poland.

In a joint statement, representatives of five Security Council members — Denmark, France, Greece, the United Kingdom and Slovenia — along with incoming member Latvia, denounced Russia's invasion of Georgia 17 years ago and its continued military presence in the country's Abkhazia and South Ossetia regions.

Poland's Deputy Prime Minister and Defense Minister Wladyslaw Kosiniak-Kamysz confirmed that the object, which fell into a cornfield near the village of Osiny, was a Russian unmanned aerial vehicle.
