Ukrainian President Volodymyr Zelensky told a meeting of G7 leaders that "common efforts to create an air shield for Ukraine" must be intensified following a barrage of Russian cruise missile and drone attacks.

At a virtual meeting of G7 heads of government on Tuesday, Zelensky said the Russians had used more than 100 cruise missiles against Ukraine since Monday and that "every ten minutes I receive a message about the enemy's use of Iranian "Shaheds [drones]."

Zelensky claimed Russia had ordered 2,400 "Shaheds" from Iran. 

The Ukrainian president said the Russian leader "still has room for further escalation."

Zelensky appealed for an "air shield for Ukraine," saying that "when Ukraine receives a sufficient number of modern and effective air defense systems, the key element of Russian terror — missile strikes — will cease to work."

Zelensky thanked Germany and the United States for systems that were being delivered and hoped a Defense Ministers meeting in Germany on Wednesday would discuss the integration of these systems with Ukraine's.

More details from the meeting: Zelensky also reiterated his demand for Russia to be declared a terrorist state and further sanctions. "We must block its energy sector with sanctions, break the stability of Russian revenues from oil and gas trade. A tough price cap is needed for the exports of oil and gas from Russia — zero profit for the terrorist state," he told the G7 leaders.

Zelensky said that "there can be no dialogue with this leader of Russia, who has no future."

He also claimed that Russia was trying to drag Belarus into the conflict. 

"The territory of Belarus is already used for strikes against Ukraine. And now we see a bigger threat. Russia is trying to directly draw Belarus into this war, playing a provocation that we are allegedly preparing an attack on this country."

He said Ukraine had no such plans and suggested a mission of international observers to be stationed on the border of Ukraine and Belarus to monitor the security situation.
