Former United States President Joe Biden was confronted by anti-Israel protesters on Tuesday during a visit to Trinity College Dublin, where his son, Hunter Biden, received an award.

According to Northern Nigeria Hub, Biden attended the event alongside his wife, Jill, as Hunter received the Gold Medal for Outstanding Contribution to Public Discourse.

Protesters gathered outside the university during the ceremony and shouted slogans against Biden over his administration’s support for Israel. As he emerged from the building, an object was thrown in his direction but was blocked by an umbrella held nearby.

Irish police arrested two people following the incident, while security personnel escorted Biden into a waiting vehicle. His motorcade subsequently left the venue.

Videos of the incident showed protesters chanting, “Blood, blood, blood on your hands!” They also shouted, “Shame on you!” at police officers as Biden was driven away.
