Green Party leader Roderic O'Gorman has said Israel has put the world on notice that it intends to ethnically cleanse Gaza.
Earlier this week, Israel's Finance Minister Bezalel Smotrich said that a victory for Israel in Gaza means that the Palestinian territory will be "entirely destroyed" before its inhabitants depart for other countries.
Following that, the foreign ministers of Ireland, Iceland, Luxembourg, Norway, Slovenia and Spain expressed their "grave concern" about a further military escalation in Gaza, saying it would "only exacerbate an already catastrophic situation for the civilian Palestinian population and threaten the lives of the hostages that remain in captivity".
Speaking on RTÉ's The Week in Politics, Mr O'Gorman urged the Government to quickly pass the Occupied Territories Bill, which he said would reverberate internationally and mark a significant change in approach.
There is no reason why this cannot happen before the summer recess, he said.
Meanwhile, Tánaiste Simon Harris has been in contact with his Dutch and Spanish counterparts with a view to working more collaboratively at an EU level to advance a review of the EU-Israel association agreement.
In tandem with progressing the Occupied Territories Bill, Mr Harris believes that diplomatic efforts must accelerate to grow the coalition within the EU seeking to use every lever available to it to support the people of Gaza.
Minister of State Hildegarde Naughton said the Government will progress the Bill, but it must be done in a way that is legal.
"We are absolutely committed to doing this. We need to get this right. This is not a policy difference," she insisted on the same programme.
Minister Naughton said the Tánaiste has held discussions with his counterparts in the Netherlands and Spain this morning "to grow the EU coalition" to support the people of Gaza.
The minister signaled that she would not have a problem with publishing the Attorney General's advice on the legal difficulties he has identified around including a ban on service in the Occupied Territories Bill.
This distinction has been described by Opposition parties as a delaying tactic.
Sinn Féin TD John Brady said that if international law means anything there has to be consequences for Israel.
As well as the swift passing of the Occupied Territories Bill, he said the Government should stop the selling of Israeli war bonds through the Central Bank as well as enacting Israeli Settlement Divestment Bill.
Aontú TD Paul Lawless said that this country has a reputation for peace and neutrality and it should be centrally involved in trying to broker a peace deal rather than "standing back from the conflict."

Meanwhile, Labour leader Ivana Bacik has said more needs to be done by the Irish State - including enacting the bill without delay.
Speaking at the annual James Connelly commemoration at Arbour Hill cemetery this morning, she said the party will "be pressing to have some further progress before the summer".
"We see again, more tragic deaths today, more reports, deeply distressing reports of children dying by starvation in Gaza under Israel's denial of aid, we've described it as a genocide - I don't think that's too strong," she said.
"I think when we hear our own Taoiseach and Tánaiste describing Israel's actions as war crimes, we do need to ensure that more is done by the Irish State."
