King Abdullah II of Jordan says his country dropped aid by parachute into northern Gaza at midnight.

"Our fearless air force personnel air-dropped at midnight urgent medical aid to the Jordanian field hospital in Gaza," read a post on X (formerly Twitter). "This is our duty to aid our brothers and sisters injured in the war on Gaza. We will always be there for our Palestinian brethren."

The king posted two photos of a crate with the flag of Jordan on it being loaded onto an airplane.

The Israel Defense Forces said Sunday it had "reached the seashore in the southern part of the city of Gaza and encircled the city of Gaza," calling the encirclement a "significant step" in the fight against Hamas.

"We will continue to attack strongly and continue to intensify our ground operation in the northern Gaza Strip and Greater Gaza City," the IDF said.

The IDF is still urging residents in northern Gaza to move south.

"We are intensifying our attack and this is already happening tonight significantly," the IDF warned.

Israeli Prime Minister Benjamin Netanyahu said Sunday at the Ramon Air Force Base in Israel that "there will be no cease-fire without the return of the hostages."

Israeli officials say 241 people have been taken hostage.

Secretary of State Antony Blinken traveled to Iraq to meet with Iraqi Prime Minister Mohammed Shia al-Sudani on Sunday following the secretary's visits to Israel, Jordan and the West Bank.

Blinken told reporters that his meeting with the Iraqi prime minister was productive and said he emphasized the need to prevent spillover from the conflict in Gaza.

"I made very clear that the attacks, the threats coming from militia that are aligned with Iran are totally unacceptable," Blinken said. "We're not looking for conflict with Iran. We've made that very clear. But we'll do what's necessary to protect our personnel."

"We're working very hard to make sure that the conflict in Gaza does not escalate, does not spread to other places, whether it's here, whether it's elsewhere in the region," he said.

Blinken was asked about Arab leaders' instance that nothing short of a total cease-fire would be acceptable.

"I think everyone would welcome humanitarian pauses -- there's no doubt about that," Blinken responded.

He said pauses "advance things that we're all trying to accomplish," including getting more humanitarian aid into Gaza, getting people out of Gaza and getting hostages home.

On his meeting with Palestinian Authority President Mahmoud Abbas, Blinken said the PA was "playing a very important role right now in the West Bank in trying to keep stability there."

Israeli officials released a statement Sunday following reports, including from The Associated Press, that hundreds of people stormed the Makhachkala main airport and landing field in southern Russia to protest the arrival of a flight from Tel Aviv. The AP cited Russian news agencies and social media.

"The State of Israel takes seriously attempts to harm Israeli citizens and Jews everywhere," the Israeli Prime Minister's Office and Ministry of Foreign Affairs said in a joint statement Sunday.

"The Prime Minister's Office, the Ministry of Foreign Affairs and the National Security Headquarters (NSH) are monitoring the development of events in southern Russia in the Dagestan province," it continued. "Israel expects the Russian law enforcement authorities to protect the safety of all Israeli citizens and Jews wherever they may be and to act resolutely against the rioters and against the wild incitement directed against Jews and Israelis."

"Israel's ambassador to Russia, Alex Ben-Zvi, is working with the authorities in Russia to ensure the safety of Israelis and Jews there," the joint statement read.

The Russian Federal Air Transport Agency said, "The measures are in effect until the situation normalizes. Law enforcement agencies are working on the spot," adding that "the planes that were supposed to land in Makhachkala were redirected to alternate airfields."

In a statement, Sergei Melikov, the head of Dagestan, said the actions of the crowd were a gross violation of the law. "There is no courage in waiting in a crowd for unarmed people who have not done anything forbidden," Melikov said. "There is no determination to break into the airport territory. There is no honor in swearing at strangers, reaching into their pockets and trying to check their passport. There are no good intentions in attacking women with children who were undergoing treatment abroad."

"What happened at our airport is outrageous and should receive an appropriate assessment from law enforcement agencies! And this will definitely be done,” he added.

More than 20 people were injured at the Makhachkala airport, the Ministry of Health of Dagestan said early Monday local time. Two people of the 10 in hospitals were in serious condition, the Ministry said. More than 10 people received medical aid at the airport.
