Ireland will recognize a Palestinian state before the end of this month if not on May 21 as first thought, Irish Foreign Minister Micheal Martin said on Wednesday.

European Union members including Ireland, Spain, Slovenia and Malta, had planned to make the recognition next week, arguing that a two-state solution is essential for lasting peace in the region.

"We will be recognizing the state of Palestine before the end of the month," Micheal Martin told Newstalk radio. "The specific date is still fluid because we're still in discussions with some countries in respect of a joint recognition."

The efforts come as a mounting death toll in Gaza from Israel's offensive to rout Hamas prompts calls globally for a ceasefire and lasting solution for peace in the region.

Since 1988, 139 out of 193 U.N. member states have recognized Palestinian statehood.

Martin said he was consulting with his counterparts in other countries to finalize the details before formally recognizing a Palestinian state.

"We're doing it in the context of the Arab peace initiative, the track towards the two-state solution and to send a signal to the Palestinian population at large that we support the right to self-determination," he said.
