In view of the advance of Russian troops in the east of his country, Ukrainian President Volodymyr Zelenskyy thanked the EU for the planned new sanctions package and at the same time called for new punitive measures.

“Ultimately, there should be no significant economic ties between the free world and the terrorist state,” he said in his video speech published on Tuesday evening. “We will work on new restrictions against Russia for this war.”

Thanks to the EU’s planned oil boycott, Russia is losing “tens of billions of euros” that can no longer be used to finance terrorism. At the same time, Zelenskyi reiterated his demands for the delivery of heavy weapons to the West.

Meanwhile, the US government announced that it would deliver modern multiple rocket launchers as part of a new security package. Wednesday is the 98th day of the war. Russia attacked neighboring Ukraine on February 24.

As soon as these heavy weapons are available, the army should start liberating the territories occupied by Russia. Ukraine will not rush to recapture its territories if that means tens of thousands of victims, but will instead wait for the necessary weapons, Zelenskyy said in Kyiv at a meeting with Slovak President Zuzana Caputova.

For weeks he has been demanding the delivery of heavy weapons from the West in order to ward off the Russian attacks in eastern Ukraine and push back the Russian troops.

The US government will deliver advanced missile systems to Ukraine, according to President Joe Biden. Biden wrote in an op-ed for the New York Times published Tuesday evening (local time) that the attacked country should be able to hit “key targets on the battlefield in Ukraine” more precisely.

At the same time, Biden assured: “We do not want a war between NATO and Russia.” The USA also did not try to overthrow Russian President Vladimir Putin.

The White House said on Tuesday evening (local time) that Ukraine had pledged not to attack targets on Russian territory with the US-made HIMARS artillery system.

The system is part of a $700 million package that also includes missiles, radar systems, Javelin anti-tank weapons, helicopters, vehicles and spare parts. A senior US official said the US would supply missiles with the HIMARS system that would only have a range of around 80 kilometers.

In the eastern Ukrainian region of Luhansk, Russian troops are poised to overthrow the last bastion of Ukrainian forces. If the embattled regional capital Sievjerodonetsk falls, Russia would have achieved one of its war aims: complete control of the Luhansk region. From there, the Russian troops and the Moscow-loyal separatists could advance further west to capture the strategically important cities of Sloviansk and Kramatorsk in the Donetsk region.

During the fighting in Sieverodonetsk, an incident occurred at a nitric acid chemical plant. The Ukrainian authorities spoke on Tuesday of a Russian airstrike on the plant.

The pro-Russian separatists, on the other hand, announced that there had been an explosion there. A large plume of smoke could be seen in photos published by the Ukrainian governor of the Luhansk region, Serhiy Hajday, on his Telegram news channel.

Sieverodonetsk, the administrative center in the Luhansk region controlled by the Ukrainian authorities, has been contested for days. The leader of the People’s Republic of Luhansk, recognized by Kremlin chief Vladimir Putin as a state, Leonid Pasechnik, said that two-thirds of the city was now under the control of pro-Russian forces.

Ukraine’s governor Hajday said most of Sieverodonetsk is now under Russian control. Still, the Ukrainian defenders didn’t give up. Ninety percent of the city’s buildings are damaged, and 60 percent are not worth rebuilding, he said. Of the once 100,000 inhabitants, 12,000 are said to have stayed there.

President Selenskyj was combative. In his video speech he said that the Ukrainian armed forces are in a difficult situation due to the lack of weapons. Ukraine will, however, take back its territories guaranteed under international law.

After weeks of discussions at a summit in Brussels, the EU countries agreed on an extensive boycott of oil supplies from Russia. This is part of the sixth package of sanctions, further details of which are to be worked out in Brussels this Wednesday. The package could then be formally approved.

It is planned to exclude the largest Russian bank Sberbank from the communication network Swift. In addition, the state television news channel Rossija 24 and the state channels RTR Planeta and TV Center are to be banned in the EU.

The Russian state-owned company Gazprom will stop supplying gas to the Danish supplier ├śrsted and Shell Energy Europe this Wednesday. Germany is also affected. ├śrsted and Shell have informed Gazprom Export that they will not pay the bills in rubles – as requested by Moscow. Because no money had flowed for the month of April, deliveries would now be stopped.
