Russian President Vladimir Putin on Sunday said Moscow may be forced to target “objects that we haven’t yet struck” after the U.S. and U.K. promised Kyiv long-range rocket systems that the Kremlin has previously called a red line.

Putin’s comments came on the same day that Russia launched airstrikes on Kyiv. Russia targeted T-72 tanks that were donated by Western countries. The Guardian reported that these tanks were stored inside a car repair business, which Ukraine denied.

Kyiv went about five weeks since similar attacks as much of the fighting took place on the eastern edge of the country.

Politico reported that these forces struck railway facilities and infrastructure in Kyiv. Ukraine said one of the missiles fired by Russian forces just missed its Energoatom nuclear plant in Pivdennoukrainsk, about 220 south of Kyiv. The report said air raid alarms rang out across the capital and the attack “showed that Russia still had the capability and willingness to hit at Ukraine’s heart since abandoning its wider offensive across the country to instead focus its efforts in the east. One person was wounded.

The U.S. and U.K. both agreed last week to provide Ukrainian fighters with long-range missile systems after debate on whether these systems could be fired deep into Russia. Kyiv said it needs these systems to counter the Russian offensive in the Donbas.

“All this fuss around additional deliveries of weapons, in my opinion, has only one goal: to drag out the armed conflict as much as possible,” Putin said. He continued, “We understand that this supply [of advanced rocket systems] from the United States and some other countries is meant to make up for the losses of this military equipment. This is nothing new. It doesn’t change anything in essence.”
