Israel had denied three Palestinian leaders from Gaza travel visas to Ramallah. The three men, who are expected to be appointed ministers in the upcoming Fatah-Hamas unity government, asked to travel to the West Bank via Israeli territory to take part in a ceremony officially announcing the new government.

Maj. Gen. Yoav Mordechai, head of COGAT, the IDF’s civil administration in the West Bank, is said to have personally denied the requests, Israel Radio reported.

On Saturday, Palestinian Authority President Mahmoud Abbas stated that the new Palestinian unity government would be announced on Monday. Abbas said that following some delay over who would lead the foreign ministry, leaders of the new government would be formally presented at the start of the week.

He also added that Israel informed the Palestinians that it would “boycott the government.” Israel has begun implementing punitive measures on the PA as a result of the unity agreement.

Abbas threatened Israel that he and his new government would “react to any Israeli action” that Israel may take against the new government, such as withholding some $100 million in monthly taxes and customs Israel collects on behalf of the PA.

“They are going to withhold our money,” Abbas said. “This is our money, not aid from Israel, and we will not stay silent. They want to punish us because we have agreed with Hamas on this government, which is part of our people.”

However, a Hamas spokesman said on Sunday that the two sides have yet to finalize the agreement. Sami Abu Zuhri said that new reports of launching the new government on this week were “unilateral” and that “there is still disagreement over some points that need to be addressed,” Ma’an News Agency reported.

In April, rivaling Palestinian factions Hamas and Fatah announced a reconciliation agreement seeking to form a united front against Israel. Gaza-based Hamas, an Islamist terror organization, has vowed to destroy Israel and refuses to renounce violent.

Under the deal, brokered by political leaders from both sides, an “independent government” of technocrats would usher in a new area for Palestinians, as well as long delayed elections.

Upon announcement of the unity agreement, Israel formally cancelled all peace negotiations with the Palestinians, saying it would not negotiate with any government backed by Hamas. Israel has imposed various diplomatic and economic sanctions on the PA while the US has threatened to cut all aid.
