Irish campaigners have called for a boycott of Israeli goods until the blockade of Gaza 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.
Members of the group continued a protest outside the Israeli embassy in Dublin today, where they called for an end to the blockade of Gaza, and for the expulsion of the Israeli ambassador, Dr Zion Evrony.
Israel's cabinet convened today to ratify an Israeli inquiry into the raid on the aid flotilla. The commission will include two foreign observers, but falls short of international calls for an impartial investigation.
Labour Party spokesman on human rights Joe Costello said the decision was "a whitewash and totally unacceptable".
"The ships were boarded in international waters by the Israeli army, nine people were shot by the Israeli soldiers, the ships were compelled to go to an Israeli port, remain in Israel custody and their crews and aid activists deported.
"These are the uncontested facts of Israeli involvement in an extremely serious incident. An internal Israeli inquiry into such an international incident with such profound Israeli involvement is quite simply ridiculous."
Mr Costello said the international community must be centrally involved and in control of the inquiry. The United Nations, the Quartet or the European Union should be in charge.
Separately, the International Committee of the Red Cross (ICRC) said today that Israel's blockade of the Gaza Strip violates the Geneva Conventions and called for its lifting.
The humanitarian agency also urged Hamas militants holding Israeli soldier Gilad Shalit, captured nearly four years ago in a cross-border raid, to allow his family to have regular contact with him, in line with international law.
Israel's raid on a Gaza aid flotilla two weeks ago, in which nine pro-Palestinian Turkish activists were killed, highlighted acute hardships faced by 1.5 million Gazans due to the closure since 2007, it said. They endure unemployment, poverty and warfare, and health care whose quality is at an "all time low".
"The whole of Gaza's civilian population is being punished for acts for which they bear no responsibility. The closure therefore constitutes a collective punishment imposed in clear violation of Israel's obligations under international humanitarian law," the ICRC said in a five-page statement.
It was the first time the ICRC has said explicitly that Israel's blockade constitutes a violation of international humanitarian law embodied in the Geneva Conventions, an ICRC spokeswoman said. The Fourth Geneva Convention of 1949, ratified by Israel, bans collective punishment of a civilian population.
