The Republic's minister for foreign affairs Micheal Martin will renew calls for an international probe into Israel's bloody raid on the Gaza aid flotilla when he meets with EU counterparts.
Mr Martin has requested that the deadly May 31 attack be added to the agenda at the monthly gathering of foreign ministers in Luxembourg.
The representatives will discuss the events leading up to the nine deaths on Turkish ship the Mavi Marmara, and Israel's ongoing blockade of Gaza.
"The key issue on the foreign policy side is Gaza and the Middle East peace process, in the aftermath of the Israeli seizure of the humanitarian flotilla," a spokeswoman said.
"The Minister will stress the need for a credible, transparent international investigation of the events, and re-emphasise the urgent need for Israel to lift the blockade to ease the humanitarian suffering of the people of Gaza."
Meanwhile, campaigners have called for a boycott of Israeli goods until the blockade ends.
Activists from the Irish Anti-War movement have vowed to continue holding demonstrations after taking their campaign to some of the capital's busiest supermarkets this weekend.
Joining the group as they loaded shopping trolleys with Israeli produce was Libyan-born Isam Bin Ali, one the Irish citizens deported from the Gaza Freedom flotilla.
