Radosław Sikorski made the appeal on the X social media platform on Wednesday morning.
Poland's top diplomat wrote that the international community "should respond to the latest onslaught on Ukraine" by "tightening sanctions," so that Russian President Vladimir Putin "cannot make new weapons with smuggled components."
Sikorski also called on the West to supply Ukraine with "long range missiles that will enable it to take out launch sites and command centers."
Russia on Tuesday morning launched an air attack on Ukraine's two biggest cities, Kyiv and Kharkiv, killing at least five people, according to Ukrainian officials.
On Friday, Russia launched the largest attack of the war, killing at least 39 Ukrainian civilians, the Reuters news agency reported.
More Russian air assaults on Ukraine followed on Sunday and on New Year's Day, according to news outlets.
Ukraine's President Volodymyr Zelensky said that between December 29 and January 2, Russia fired at least 500 missiles and unmanned aerial vehicles against his country.
Wednesday is day 679 of Russia’s war on Ukraine.
Russia invaded Ukraine on February 24, 2022, launching the largest military campaign in Europe since World War II.
