Russia said on Thursday ‌it would keep increasing pressure on Ukraine, following a massive overnight strike on Kyiv that killed at least 17 people and wounded scores.

Ukraine said Russia launched 74 missiles and 496 drones in the attack, which destroyed a number of residential ‌buildings. Kremlin spokesman Dmitry Peskov said it had been ​aimed exclusively at "military or quasi-military targets."

Peskov said President Vladimir Putin had been briefed by his top military commander, Valery Gerasimov, ⁠on the results of what he called a "massive retaliatory strike" against ​Kyiv and other locations.

In the fifth year of the war, Russia ⁠has stepped up its missile and drone attacks, especially on Kyiv, as Ukraine has intensified its own drone strikes on Russia's energy sector, inflicting heavy damage that has led ‌to widespread fuel shortages.

Asked about a statement by European Union ​foreign policy chief Kaja ‌Kallas that the EU would propose yet more sanctions to step up pressure on Russia, ‌Peskov replied: "Russia will continue to intensify pressure on the Kyiv regime in order to achieve the goals it has set."

Peskov said a discussion ⁠was taking place in Russia ‌over how to protect ⁠its security in response to what Moscow sees as steps by the EU to "militarize" ⁠the continent ⁠and increase tensions.

Some Russian hardliners, angered by Ukraine's drone strikes and by what they see ‌as a failed U.S. promise to broker an end to the war on favorable terms, have urged Putin in recent weeks to abandon diplomacy and ‌escalate.

"You are ​aware that there ‌are proponents, including academics, of very drastic measures, just as there are advocates for more restrained approaches," Peskov said.

"But one thing ​is beyond doubt: the secure protection of the Russian Federation and its national interests will be guaranteed, come what may."
