On Friday, NATO Secretary-General Jens Stoltenberg condemned Russia's "recklessness" in attacking a nuclear power plant in Ukraine and demanded that Moscow end its conflict with its neighbour.
"We've also heard reports of an attack on a nuclear power station over the course of the night. This only serves to highlight the war's rashness and the need of stopping it, as well as the importance of Russia removing all of its forces and engaging in good faith diplomatic efforts "Before meeting with Western foreign ministers, Stoltenberg stated.
Allies convene in Brussels on Friday for a busy day of diplomacy, hoping to maintain pressure on Moscow following a wave of punitive sanctions over the invasion of Ukraine.
Thousands of NATO troops have been dispatched to eastern Europe to fortify the alliance's flank closest to Russia, and weapons are being sent to assist Ukraine defend itself.
NATO, on the other hand, has ruled out engaging militarily for fear of escalating into a direct confrontation with Moscow, which may result in nuclear war.
So far, this has included rejecting Ukrainian pleas for a no-fly zone to be enforced over their nation to stop Russian bombs.
"We know that our red line is to avoid international confrontation," said Melanie Joly, Canada's foreign minister.
"At the same time, I would say that we want to make sure that scenarios are considered, and we also want to make sure that we can have dialogues throughout the alliance, and across all of the nations who support Ukraine, because we need to end this war."
The ministers meeting on Friday at NATO, the European Union, and the G7 are expected to assess the impact of sanctions on Russia and consider tougher measures, including requests to target Russia's crucial oil and gas exports.
"Everything is still on the table," said Josep Borrell, the EU's foreign policy leader.
More penalties against Russian President Vladimir Putin's inner circle, according to German Foreign Minister Annalena Baerbock.
"We will take additional measures that target Putin's centre of power in addition to the three severe packages of (EU) sanctions that we have already decided on," she said.
However, significant European nations like as Germany are hesitant to target Russian energy exports, which account for around 40% of gas and 10% of oil entering the EU.
