The Warsaw Police Headquarters told PAP on Wednesday that it had received a report about an attempt to set fire to the Nozyk synagogue in Warsaw.
The police are carrying out investigation into this event, a police commissioner Jacek Wisniewski said.
President Andrzej Duda condemned the "shameful attack."
"There is no place for anti-Semitism in Poland! There is no place for hatred in Poland!" he wrote on the X platform on Wednesday.
Foreign Minister Radoslaw Sikorski, quoting Poland's chief rabbi, Michael Schudrich, wrote on the X that "someone tried to set fire to the Nozyk synagogue with a Molotov cocktail."
"Thank God no-one was hurt," he added.
"I wonder who is trying to disrupt the anniversary of our accession to the EU. Maybe the same ones who scrawled the Stars of David in Paris?" Sikorski wrote.
The US Embassy in Poland also commented on the incident on the X platform.
"The US mission in Poland strongly condemns the attack on the Nozyk Synagogue in Warsaw. We stand in solidarity with the members of the Synagogue and the whole Jewish community in Poland. We support all those who work to fight anti-Semitism," it wrote.
Nozyk Synagogue is the only preserved and functioning pre-war synagogue in Warsaw. The building has been undergoing renovations since 2008, with the roofing replaced and the damaged wooden structure repaired. (PAP)
