The Government is under pressure to express greater concern about the escalating violence in Gaza.
Sinn Féin are describing as "shameful", the Taoiseach Enda Kenny's refusal to postpone the Dáil's summer break to hold a debate on the issue.
Instead, a minute's silence was held in the Dáil chamber, before TDs took their summer holidays yesterday.
Fianna Fáil, meanwhile, says the Taoiseach should call in the Israeli Ambassador and express the country's "revulsion" at events in Gaza.
Party leader Micheál Martin says Ireland has a moral duty to oppose what he described as "pointless slaughter".
