Iran Press/ Europe: More than 100 people staged the demonstration near the Spire on O'Connell Street this afternoon.
The British Prime Minister Kier Starmer is in Ireland to meet Taoiseach Simon Harris and Irish business representatives.
The Irish-Palestine Solidarity Campaign (IPSC) said it was staging the demonstration to "let the visiting British Prime Minister know that Ireland stands with Palestine".
Speaking at the event, IPSC spokesman Harun Siljak said the group was asking Starmer "to end British complicity in the ongoing genocide and illegal occupation of Palestine".
Demonstrators, some wearing keffiyehs, waved Palestinian and Irish flags as they chanted slogans including "free, free Palestine".
The IPSC said the recent suspension of 30 arms export licences to Israel is a "testament to the tireless work" of Palestine solidarity activists in the UK. 219
