Israel on Monday hosted the foreign ministers of four Arab nations and the United States in a bid to strengthen its position in a rapidly shifting Middle East.

The gathering brought together the top diplomats from all but one of the Arab countries that have normalized relations with Israel in U.S.-mediated negotiations, including three that signed the so-called Abraham Accords during the Trump administration in 2020.

The militant Islamic State group claimed responsibility on Monday after a pair of Arab gunmen killed two people and wounded four in central Israel before they were killed by police.

The two killed in the Sunday night attack were Israeli police officers, authorities said.

The U.S. and Israel are committed to ensure Iran does not acquire a nuclear weapon, Secretary of State Antony Blinken said Sunday, as the allies acknowledged differences over negotiations with Tehran.

"When it comes to the most important element, we see eye to eye. We are both committed, both determined, that Iran will never acquire a nuclear weapon," Blinken told reporters in Jerusalem, alongside his Israeli counterpart Yair Lapid, who said Israel had "disagreements" with Washington about a possible deal to revive the 2015 nuclear accord with Tehran.

Russia's war on Ukraine has drawn unprecedented sanctions that have seen it banned from most international sports in a Western-led break with the long-standing convention against politics mixing with sport.

Iran, under sweeping economic sanctions, was hawking weapons on Wednesday at a Qatari defense exhibit, a surprising sight at the major conference also showcasing American companies and fighter jets.

Tucked away in the far left corner of the carpeted convention center, commanders from Iran's defense ministry marketed their missiles and air defense weapons systems. The defense ministry manufactures arms for both Iran's military and its powerful paramilitary Islamic Revolutionary Guard, a group that plays a singular role in the creation and execution of Iran's national security and foreign policy.

The foreign ministers of Iran and Syria, two allies of Russia, discussed the war in Ukraine and other developments during a meeting in Damascus on Wednesday. Syria's top diplomat said Moscow is defending its people.
