Iran described as "regrettable" Tuesday a decision by the European Union to expand the bloc's sanctions against its weapons programs in response to its unprecedented retaliatory attack on Israel.

"It is regrettable to see the EU deciding quickly to apply more unlawful restrictions against Iran just because Iran exercised its right to self-defense in the face of Israel’s reckless aggression," Foreign Minister Hossein Amir-Abdollahian said in a post on X.

Satellite photos analyzed by The Associated Press appear to show a new compound of tents being built near Khan Younis in the Gaza Strip as the Israeli military continues to signal it plans an offensive targeting the city of Rafah.

Images from Planet Labs PBC analyzed by the AP show the tent compound starting to be fully under construction on April 16 just west of Khan Younis. Images taken Sunday show the tent compound in the time since has grown.

Qatar is in a “reevaluation phase” when it comes to trying to mediate talks between Israel and Hamas over a cease-fire in the Gaza Strip.

Satellite photos taken Monday suggest an apparent Israeli retaliatory strike targeting Iran's central city of Isfahan hit a radar system for a Russian-made air defense battery, contradicting repeated denials by officials in Tehran of any damage in the assault.

The strike on an S-300 radar in what appears to have been a very limited strike by the Israelis would represent far more damage done than in the massive drone-and-missile attack Iran unleashed against Israel on April 13. That may be why Iranian officials up to Supreme Leader Ayatollah Ali Khamenei have been trying to dismiss discussing what the attack actually did on Iranian soil.

An independent review of the neutrality of the U.N. agency helping Palestinian refugees found that Israel never expressed concern about anyone on the staff lists it has received annually since 2011. The review was carried out after Israel alleged that a dozen employees of the agency known as UNRWA had participated in Hamas' Oct. 7 attacks.

In a wide-ranging 48-page report released Monday, the independent panel said UNRWA has "robust" procedures to uphold the U.N. principle of neutrality, but it cited serious gaps in implementation, including staff publicly expressing political views, textbooks used in schools the agency runs with "problematic content" and staff unions disrupting operations. It makes 50 recommendations to improve UNRWA's neutrality.

On October 7, Palestinian militants launched an attack on southern Israel that resulted in the deaths of 1,170 people, mostly civilians, according to an AFP tally based on official figures.

Prime Minister Benjamin Netanyahu's government responded to the worst attack in the country's history with a devastating military campaign in the Gaza Strip, ruled by armed group Hamas, that has killed 34,151 people, mostly women and children, according to the Palestinian territory's health ministry.

Jewish people mark on Monday the start of Passover, a celebration of freedom, and around many holiday tables in Israel chairs will stand empty for hostages still held captive in Gaza.

The week-long Jewish festival, also known in Hebrew as the "holiday of freedom", celebrates the Israelites' liberation from Egyptian slavery, as told in the Bible.

Turkish President Recep Tayyip Erdogan arrived in Iraq on Monday for his first official visit in more than a decade as his country seeks greater cooperation from Baghdad in its fight against a Kurdish militant group that has a foothold in northern Iraq.

Other issues also loom large between the two countries, including water supply issues and exports of oil and gas from northern Iraq to Turkey, which have been halted for more than a year.

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.
