Jason Greenblatt, U.S. President Donald Trump's Special Representative for International Negotiations, on Monday blasted the Hamas terrorist group in a series of tweets.

“Hamas literally undermines Gaza’s chance for success— now building a terror tunnel under a crossing to Israel that should be a conduit toward a better economy,” he wrote.

“A terror tunnel costs roughly $5.9 million to build ($ that belongs to the people of Gaza) plus roughly $30,000 a day in lost revenue when the crossing is closed as a result. Gaza needs options besides Hamas and its enablers. Time to stop pouring money into violence and hatred, and to start investing in a real future for Palestinians in Gaza,” added Greenblatt.

The tweets mark the second day in a row that Greenblatt, who is currently holding a series of meetings with Israeli officials, criticized Gaza's Hamas rulers.

On Sunday, Greenblatt toured the Israel-Gaza border area, accompanied by the IDF’s Coordinator of Government Activities in the Territories (COGAT) Major General Yoav Mordechai.

Greenblatt visited one of the recently discovered Hamas terror tunnels, which extends from Gaza into Israel, and received a comprehensive security briefing regarding the threats emanating from Gaza.

Shortly after the tour, Greenblatt tweeted his condemnation of Hamas, saying the terror group “wastes resources” on terror rather than investing in the Gaza Strip’s civilian needs.

“Hamas wastes resources on tunnels & rockets to attack Israel, instead of helping the people of Gaza by getting the lights on, the water flowing & the economy growing. Hamas spews hateful rhetoric & foments a vicious cycle of violence. Gaza deserves better!”
