Iranian Muslims travelled Monday to Saudi Arabia for umrah, a year-round pilgrimage they had been barred from for almost a decade over a rift between Tehran and Riyadh, Iranian state media said.

"The first group of umrah pilgrims departed Iran for Saudi Arabia through the Imam Khomeini airport in Tehran", official news agency IRNA reported.

Israeli strikes on the southern Gaza city of Rafah overnight killed 22 people, including 18 children, health officials said Sunday, as the United States was on track to approve billions of dollars of additional military aid to Israel, its close ally.

Israel has carried out near-daily air raids on Rafah, where more than half of Gaza's population of 2.3 million has sought refuge from fighting elsewhere. It has also vowed to expand its ground offensive against the Hamas militant group to the city on the border with Egypt despite calls for restraint, including from the U.S.

Rockets were fired late Sunday from northern Iraq at a military base in Syria housing a U.S.-led coalition, according to Iraqi security forces.

The anti-jihadist coalition said one of its fighter jets in Iraq had "destroyed a launcher in self-defense after reports of a failed rocket attack" near a base in northeast Syria.

The Israeli military said on Monday the chief of its intelligence directorate has resigned after taking responsibility for failures leading to the unprecedented October 7 attack by Hamas.

"Major General Aharon Haliva, in coordination with the chief of the general staff, has requested to end his position, following his leadership responsibility as the head of the intelligence directorate for the events of October 7," the military said in a statement.

Gaza's civil defense said dozens of bodies had been found buried at a hospital complex previously raided by Israel, as Prime Minister Benjamin Netanyahu vowed to ramp up military pressure on Hamas.

Netanyahu, who threatened action "in the coming days" without elaborating, has repeatedly said Israel will launch a ground assault on Rafah despite international concern for civilians who have taken refuge in the southern Gazan city.

The United States appears close to sanctioning an Israeli military unit over alleged human rights violations in the West Bank, a move the Israeli prime minister angrily denounced as "the height of absurdity."

U.S. Secretary of State Antony Blinken hinted at such steps when asked by a reporter in Italy about reports that his department had recommended cuts in military aid to an Israeli unit involved in violent incidents in the West Bank.

Turkish President Recep Tayyip Erdogan urged Palestinians to unite amid Israel's war in Gaza following hours-long talks with Hamas chief Ismail Haniyeh in Istanbul on Saturday, his office said.

Erdogan has failed to establish a foothold as a mediator in the Gaza conflict that has roiled the region, with the Hamas-run Palestinian territory bracing for a new Israeli offensive and a reported Israeli attack on Iran.

Iran and Israel appeared to step back from the brink of broader conflict as lawmakers in the United States approved new Israeli military aid despite growing criticism of its ally's war in Gaza.

Iran downplayed Israel's reported retaliation for its unprecedented drone and missile attack, tamping down fears that escalating attacks between the arch enemies could tip over into a broader war in the Middle East.

Several people were wounded in a "bombing" overnight on an Iraqi military base housing a coalition of pro-Iranian armed groups, two security sources said early Saturday.

The explosion hit the Calso military base in Babylon province south of Baghdad, where Iraq's Popular Mobilization Forces, or Hashed al-Shaabi, is stationed, according to an interior ministry source and a military official.

World leaders have appealed for calm after reported Israeli retaliation against Iran added to months of tense spillover from the war in Gaza, with Iranian state media reporting explosions in a central province.
