The Wall Street Journal revealed European moves to hold an international summit not attended by Moscow, with the aim of reformulating the Ukrainian peace plan, while Russia and Ukraine exchanged air attacks with drones on the capitals of the two countries.

The newspaper, citing a senior Ukrainian presidential adviser and European diplomats, said Ukraine and its allies were planning a summit of world leaders not attended by Russia, aimed at rallying support for Kiev's conditions for ending the war.

The summit plan has strong support from European leaders, France, Denmark and Sweden have offered to host it, and European leaders, including French President Emmanuel Macron, are pushing for the participation of countries that have sided with Russia or refused to take a position on the war.

Wall Street quoted European diplomats as saying that Ukrainian President Volodymyr Zelensky earlier this year asked his French counterpart for help with international outreach to leaders such as Chinese President Xi Jinping.

There are efforts with Kiev to reformulate Ukraine's 10-point peace plan, in a way that makes it more acceptable to other world powers such as India, Brazil, Saudi Arabia and China.

Nuclear dangers

In a related context, the head of the International Atomic Energy Agency Rafael Grossi on Tuesday called on both Russia and Ukraine to adhere to five "concrete principles" to ensure the safety of the Zaporizhia nuclear plant and avoid a "nuclear accident."

"We are fortunate that there has not been a nuclear accident yet," Grossi told the UN Security Council, recalling that the plant controlled by the Russian military had been cut off from the power grid seven times and had to rely on emergency generators to cool the reactor, which is "the last line of defense in the face of a nuclear accident."

The principles proclaimed by Grossi include: avoiding an attack of any kind from or on the plant, avoiding the site being used to store heavy weapons or military buildup, and not disconnecting the plant from the power grid.

The Zaporizhia plant, the largest in Europe, is located on the banks of the Dnipro River separating the two camps in this region, and has been repeatedly targeted and cut off from the electricity grid 7 times since the Russian army took control of it on March 4, 2022.

Czech warning

In a remarkable statement, Czech Chief of the General Staff Karel Rika warned of the possibility of a clash between Russia and NATO.

In a speech to the Czech parliament, Rika said such a bad scenario seemed possible, and that Russia was on a path that could lead to such a conflict.

He added that NATO armies must seriously prepare for the possibility of a direct military conflict with Moscow.

War of the marches

On the ground, Russia and Ukraine have exchanged drone air attacks on the capitals of the two rival states for more than 15 months, in a new development of the war.

The Russian capital Moscow was attacked at dawn on Tuesday by drones, causing "minor" damage to several buildings and injuring two people, after a large-scale drone attack on the Ukrainian capital Kiev for the third time in 24 hours, killing one person and injuring 4 others.

Russian President Vladimir Putin confirmed that the unprecedented drone attack on Moscow at dawn on Tuesday came in response to a Russian strike on the headquarters of Ukrainian military intelligence.

On the other hand, the Russian military website Ribar said that the attacks on Moscow were using UJ-22 drones owned by Ukrainian forces.

Adviser to Ukraine's president Mykhailo Podolyak denied Kiev was directly involved in a drone attack on Moscow on Tuesday, but said his country was enjoying watching the matter and predicted an increase in such attacks.

For its part, the United States said Tuesday that it does not support carrying out attacks inside Russia, but said Moscow bears responsibility for the war on Ukraine.

A State Department spokesman said the United States was still assessing what happened in Moscow, where residential buildings were targeted for the first time since Russia's attack on Ukraine, and Russian President Vladimir Putin was held responsible.

Massive attack

Kiev's mayor said a woman died and at least 11 others were wounded on Tuesday in Russia's third attack on the Ukrainian capital in 24 hours.

Ukraine shot down more than 20 Russian drones, officials said, as part of what the head of Kiev's military administration, Sergei Bubko, described as a "massive attack" carried out in several stages and from different directions.

In May, Russia launched 17 air strikes on Kiev, mostly overnight, and Ukrainian officials say the strikes are aimed at causing panic and weakening air defenses ahead of an expected Ukrainian counteroffensive.
