The Trump administration's global negotiations representative, Jason Greenblatt, on Monday called on the terror group to tone down its war rhetoric, tweeting, "Extremist statements & provocation vs. Israel by Islamic Jihad significantly harm the people of Gaza & are very unsafe".
The U.N. also voiced its concern about the threat of an imminent attack by the Islamic Jihad and the potential repercussions, in particular on an ongoing reconciliation process between the leading Palestinian factions Fatah and Hamas to bring Gaza back under the control of the internationally recognized Palestinian Authority.
Israel has always been concerned about the use of tunnels built by Hamas to both store weapons and infiltrate fighters into the country. The majority of the two million Palestinians in the Gaza Strip are sealed inside the coastal enclave due to the continuation of the military blockade imposed by Israel and upheld by Egypt on the southern border. "It has many tunnels and many options", senior PIJ member Ahmad al-Mudalal warned. "In any case, we see Hamas as responsible for every attack that emanates from, or is planned against us in, the Gaza Strip", he said.
