Ukrainian Foreign Minister Dmitro Kuleba said on Friday that his country would start collecting data on the actions of the Russian armed forces during the invasion of Ukraine, to send them to the International Criminal Court (ICC).

"Today's Russian attacks on a kindergarten and an orphanage are war crimes and violations of the Rome Statute," Kuleba wrote on Twitter, adding that these and other acts would be sent to the ICC.

"They will not escape punishment," he continued, insisting that the Ukrainian Foreign Ministry is gathering evidence with the Prosecutor General to send it "immediately to The Hague."

Authorities in Kiev have accused Russian troops of attacking Russian installations since the start of Russia's military offensive on Thursday, allegations denied by the Russian Defense Ministry.

Ukrainians are shocked and horrified by what is happening to them. Sirens are heard in Kiev, and people are fleeing the city. Images appeared with huge columns of cars blocking the highway at the exit from Kiev. Meanwhile, others have taken refuge in subway stations or are kneeling on the streets.

On social media, people send messages saying that they are panicking and that they are trying to get to anti-aircraft shelters and basements as soon as possible. Reporters filmed groups of people praying on the street, kneeling.

Russia is also using Belel air base in Belarus to mobilize troops to storm Kiev over damage to Hostomel military airport near the Ukrainian capital, the Ukrainian Armed Forces General Staff said on Friday, according to Reuters.

"In order to intimidate the population of Ukraine, the enemy is increasingly choosing to destroy civilian infrastructure and housing," the staff said in a Facebook post.

According to the General Staff, Russian troops are advancing towards Kiev in several directions, while Ukrainian forces are fighting around the city of Mariupol in the south and in Kharkov in the northeast of the country.

In parallel, the Ukrainian Ministry of Defense announced that the first units of the Russian army have entered Kiev, according to DPA.

Russian "saboteurs" have entered the Obolon district, in the north of the capital, the ministry announced on its Facebook page.

The Ukrainian Ministry of Defense has asked locals to prepare Molotov cocktails and announce the appearance of Russian army equipment.

At the same time, according to Reuters, gunfire was reported in the government district of Kiev, the RIA reported.

NATO Secretary-General Jens Stoltenberg has called on Russia to withdraw from Ukraine and return to dialogue. He says the Kremlin's goals are not limited to Ukraine and that Russia is challenging the European security order.

"We call on Russia to stop this meaningless war, to withdraw all forces from Ukraine and return to the path of dialogue," Stoltenberg said after an online summit of NATO leaders.

"The Kremlin's goals are not limited to Ukraine. Russia has demanded that we renounce NATO enlargement and remove troops and infrastructure from countries that joined the alliance after 1997. Russia is challenging the European security order and using force to achieve its goals, "he said.

Stoltenberg recalled that the United States, the EU and other Western countries had taken harsh sanctions against Russia.

"We have to be ready to do more, even if we have to pay the price," he said.

The NATO chief also sent a message to the Russians.

"The Russian people need to know that the Kremlin war in Ukraine will not make Russia safer, more respected abroad, and will not lead to a better future," Stoltenberg said.

"In response to the build-up of Russian soldiers, we have stepped up our defense. Yesterday, the Allies activated their defense plans. As a result, we send rapid response elements on land, at sea, in the air, to strengthen the flank and respond quickly. The United States, Canada, and the EU have sent thousands of troops to the East Side. We have over 100 aircraft on high alert, 120 ships from the north to the Mediterranean, ”Stoltenberg continued.

"We are now deploying NATO's reaction force for the first time in the context of collective defense," the NATO chief added.

Stoltenberg added that NATO allies will continue to support Ukraine.

Several US cities are under siege.  Anti-racism protests continued on Tuesday (June 2nd), after Donald Trump threatened protesters to take the army out into the streets.

In fact, the Pentagon moved about 1,600 U.S. Army soldiers to the Washington, D.C. region after nights of protests and violence, Digi24 reports.  Eight days after George Floyd's death, protests against racism and police brutality and social inequality do not seem to end too soon.  People are more determined than ever to demand their rights in the streets, but President Donald Trump has told protesters he will use whatever means necessary to stop the protests.  This threat provoked an even bigger wave of anger.

 Thus, on Tuesday evening (June 2), thousands of people, including Democratic Senator Elizabeth Warren, peacefully defied the traffic ban in the federal capital Washington.  The area around the White House has been blocked by barriers.

 Also, at least 60,000 people paid their last respects to George Floyd at a peaceful rally in Houston, Texas, where he grew up and where he will be buried next week.  The 45-year-old African American was killed by a white policeman.  He was unarmed and in police custody when an officer kicked him in the neck for minutes while George Floyd begged for his life.  The tragedy was filmed and angered the community of people of color, who have been facing police brutality for years.

 In Manhattan, several thousand protesters gathered to protest peacefully near the New York police headquarters.

 On Tuesday night, the situation was calm in Minneapolis, the epicenter of this wave of revolt that spread to more than a hundred American cities and resulted in thousands of arrests and several wounded among police and protesters.
