Polish Interior Minister Marcin Kierwiński said on X that he had instructed officials to begin the process of placing Ben-Gvir on Poland's list of undesirable foreign nationals.
The move came after Deputy Prime Minister and Foreign Minister Sikorski formally requested the ban, state news agency PAP reported.
EU foreign policy chief Kaja Kallas said the treatment was "degrading and wrong" and that Ben-Gvir’s behaviour was "unbecoming of anyone holding office in a democracy."
Even the US ambassador to Israel, Mike Huckabee, known for his pro-Israel views, said the minister's "despicable actions" had "betrayed the dignity of his nation."
Israeli Prime Minister Benjamin Netanyahu said in a statement that his country "has every right to prevent provocative flotillas of Hamas terrorist supporters" from entering its territorial waters and reaching Gaza.
"However, the way that Minister Ben Gvir dealt with the flotilla activists is not in line with Israel’s values and norms," he added.
The Gaza Freedom Flotilla, an international movement seeking to challenge Israel's naval blockade of Gaza and draw attention to the humanitarian crisis there, sent around 70 vessels carrying activists from 56 countries.
Israeli forces boarded the boats in international waters, detaining more than 420 people, according to reports.
