Former Secretary of State Hillary Clinton is calling for more pressure to be placed on Russian President Vladimir Putin amid the country’s invasion of Ukraine.

Appearing Sunday on NBC's “Meet the Press,” Clinton said the key to ending the attack on Ukraine was more sanctions to punish Putin.

“The only way that we’re going to end the bloodshed and the terror that we’re seeing unleashed in Ukraine, and protect Europe and democracy, is to do everything we can to impose even greater costs on Putin. There are more banks that can be sanctioned. ... There is an increasing call for doing more on gas and oil,” Clinton said.

“So I think that now is the time to double down on the pressure," Clinton said.

Clinton claimed that failure to take action against Russia could jeopardize the future of governments around the world.

“We are really looking at this with our eyes wide open and seeing very clearly the threat he poses — not just to Ukraine, as we can watch every night on our news — but really to Europe, to democracy and the global stability that we thought we were building in the last 20 years,” she said.

Clinton’s demands to take action against Putin come after Ukrainian presidential adviser Mykhailo Podoliak shared images of bodies on the streets of Bucha, a suburb in Ukraine, with their hands tied behind their backs.

“The Ukrainian city of Bucha was in the hands of [Russian] animals for several weeks. Local civilians were being executed arbitrarily, some with hands tied behind their backs, their bodies scattered in the streets of the city,” the Ukraine defense ministry said in a statement.

On Sunday, Ukrainian President Volodymyr Zelensky said he expects the U.N. Security Council to take further action to punish Putin.

“There will definitely be a new package of sanctions against Russia. But I’m sure that’s not enough. More conclusions are needed. Not only about Russia, but also about the political behavior that actually allowed this evil to come to our land,” Zelensky said.

Germany, Poland, and other governments have already called for further sanctions against Putin amid the attacks. However, the U.N. Security Council isn’t scheduled to meet until Tuesday, when several discussions will take place, including whether Putin has committed war crimes.
