JERUSALEM/TEHERAN/NEW YORK/DOHA/UNITED NATIONS/BRUSSELS - Israeli Prime Minister Benjamin Netanyahu said Tuesday Israel accepts a ceasefire proposed by US President Donald Trump and has achieved its war goals against Iran. 

Israel reopens airspace to incoming flights after closure due to conflicts with Iran, Israel's airports authority announced Tuesday morning.

Iran's Press TV said Tuesday that ceasefire begins following waves of Iranian attacks on Israel.

Early Tuesday, Israel's military said it was working to intercept Iranian missiles launched "a short while ago," without specifying the exact time of the attack.

"A short while ago, sirens sounded in several areas across Israel following the identification of missiles launched from Iran toward the State of Israel," the military said in a statement posted on Telegram around 5:00 am local time (0200 GMT). Iran has since fired waves of missiles at Israel, according to Iranian state media.

Trump had earlier announced that a ceasefire between the two sides would begin around 0400 GMT, with Iran expected to halt its operations first.

Iranian Foreign Minister Abbas Araqchi said earlier that there was no "agreement" on a ceasefire between Iran and Israel. However, he suggested Iran would be prepared to halt further retaliation if Israeli attacks stopped by 4 am Teheran time (0030 GMT).

"If Israel stops its illegal aggression against the Iranian people no later than 4 am, Iran has no intention of continuing its response afterwards," Araqchi wrote in a post on X, adding that "the final decision on the cessation of our military operations will be made later."

Hours earlier, a senior Iranian official told CNN that Teheran had not received any formal ceasefire proposal from the United States and saw no reason to halt hostilities.

"At this very moment, the enemy is committing aggression against Iran, and Iran is on the verge of intensifying its retaliatory strikes, with no ear to listen to the lies of its enemies," the official was quoted as saying. He added that remarks from US and Israeli leaders would be seen as a "deception" intended to justify further attacks on Iran.

The conflicting narratives raised questions about the implementation and durability of any potential ceasefire. As of Monday night, neither Israeli nor Iranian officials had publicly confirmed any agreement. The White House and the Pentagon had also not issued formal statements, and it remained unclear whether the reported deal had been communicated through diplomatic channels, or whether either side intended to follow the terms.

Trump announced Monday evening that Israel and Iran have reached a formal agreement to implement a complete and total ceasefire, marking what he called the end of the "12-Day War."

In a post on his Truth Social platform Monday, Trump said the ceasefire will initially last 12 hours, during which the opposing sides will maintain a posture of "peace and respect."

"On the assumption that everything works as it should, which it will," Trump wrote, "I would like to congratulate both countries... on having the stamina, courage, and intelligence to end what should be called 'THE 12 DAY WAR.'"

Calling the agreement a breakthrough that "could have saved the Middle East from years of destruction," Trump ended his announcement with a sweeping message of unity: "God bless Israel, God bless Iran, God bless the Middle East, God bless the United States of America, and GOD BLESS THE WORLD!" 

US airbase

Hours before Trump announced the ceasefire, Qatar's air defense systems intercepted 18 of 19 Iranian ballistic missiles targeting the Al Udeid Air Base, which hosts US forces. One missile impacted inside the base without causing any casualties or material damage.

Shayeq Al-Hajri, the Qatari Ministry of Defense's deputy chief of Joint Operations, confirmed in a press conference that the missiles were launched in two separate waves. The intercepted missiles were destroyed over the sea after entering Qatari airspace.

"We received intelligence earlier in the day indicating a threat to several regional military installations, including Al Udeid," Al-Hajri stated. He emphasized Qatar's military readiness, noting that its capabilities "go beyond what has been demonstrated."

Trump on Monday confirmed that Iran had launched a missile attack on a US military base in Qatar in response to recent American airstrikes on its nuclear facilities, describing it as a "very weak response" that caused no casualties and "hardly any damage."

In a series of posts on Truth Social, Trump said 14 missiles were fired by Iran, with 13 intercepted and one allowed to proceed as it posed no threat. He credited Iran for providing "early notice," which he said enabled the United States to avoid any loss of life.

EU calls for restraint

European leaders have voiced deep concern over the escalating conflict in the Middle East, following a series of military strikes that have intensified fears of a wider regional war.

Croatian Prime Minister Andrej Plenkovic, in a statement released Monday, said the Croatian government is "monitoring the situation with great concern," particularly the direct confrontations between Israel and Iran.

He warned that further escalation could lead to a range of consequences, including rising energy prices, increased migration, and the threat of terrorist attacks.

"Our position is clear: escalation should be avoided," the statement read. "The Croatian government calls for restraint, calming of tensions, and de-escalation of the conflict."

Serbian President Aleksandar Vucic also criticized the recent US military action in the region, calling the strike on Iran a violation of international law.

"There is no doubt that the United States violated international public law," Vucic said at a press conference following a meeting of the General Staff.

Drawing parallels with the 1999 NATO bombing of Yugoslavia, he emphasized the need for respect for the UN Charter and international norms. Vucic also lamented the missed opportunity for diplomacy between Iran and Israel.

In Italy, Prime Minister Giorgia Meloni addressed the lower house of parliament ahead of the upcoming European Union Council meeting, urging renewed diplomatic engagement.

"Only coordinated diplomatic action can ensure peace in the region," she said, after the US strike on three Iranian nuclear sites.

Portuguese President Marcelo Rebelo de Sousa issued a statement on Sunday calling for "restraint and the urgent resumption of diplomatic efforts," stressing that diplomacy remains the only viable solution to the conflict.

He reaffirmed Portugal's alignment with the United Nations and the European Union in advocating for de-escalation and avoidance of further military confrontation.

Portuguese Prime Minister Luis Montenegro echoed this sentiment on social media, calling for "maximum restraint from all parties and a return to negotiations."

Meanwhile, the Portuguese Communist Party (PCP) issued a strongly worded condemnation of the US airstrikes, labeling them a "clear violation" of the UN Charter and international law. The party argued the attack reflects a broader strategy of global domination by the US and its allies.

Iran to 'suspend cooperation with IAEA'

Iran's Parliament Speaker Mohammad-Bagher Ghalibaf said on Monday the legislature is moving to approve a plan to suspend Tehran's cooperation with the United Nations nuclear watchdog, as tensions intensify with the United States and Israel.

In a post on social media platform X, Ghalibaf accused the International Atomic Energy Agency (IAEA) of lacking "professional" conduct following recent attacks on Iranian nuclear sites.

"We in the Islamic Consultative Assembly are seeking to approve a plan to halt cooperation with the agency until we receive concrete guarantees of its professional behavior," Ghalibaf said.

Citizens suspected of espionage

Israeli police have arrested three citizens suspected of espionage and security-related offenses on behalf of Iran, authorities said on Monday, as the exchange of air raids between the two countries entered its 11th day.

The three unrelated cases include a 19-year-old resident of central Israel who, according to a police statement, was arrested on suspicion of sharing classified information with an Iranian operative during the ongoing conflict. The investigation is being conducted in coordination with the Shin Bet internal security agency.
