Israeli officials have expressed shock at the attack and said they were investigating the assault on Marek Magierowski on Tuesday.
The incident comes amid a bitter standoff between Poland and Israel over how to remember the Holocaust and over demands that Poland pay reparations for former Jewish properties that were seized by Nazi Germany and later nationalised by Poland's communist regime.
"Poland strongly condemns this xenophobic act of aggression. Violence against diplomats or any other citizens should never be tolerated," Morawiecki said.
