Mediator Qatar’s said Tuesday it was working on resuming Gaza ceasefire talks in days, urging Israel not to exploit a truce with Iran to "unleash everything it wants to unleash" on the blockaded strip.

"We are still continuing our efforts, and God willing, we will try to look for an opportunity during the next two days for having indirect negotiations between the two parties... We hope that the Israeli side will not exploit the ceasefire with Iran to unleash what it wants to unleash on Gaza and continue its bombing of" the strip, said Sheikh Mohammed bin Abdulrahman bin Jassim Al-Thani during a joint press conference with his Lebanese counterpart.

An angry Donald Trump berated Iran and Israel Tuesday for violating a ceasefire deal, adding that he was "really unhappy" with Israel in particular.

The two countries have been "fighting so long and so hard that they don't know what the fuck they're doing, do you understand that?" the U.S. president told reporters at the White House, hours after he had said a ceasefire between the two arch-foes had taken effect.

Iran's Revolutionary Guards said Tuesday that they had taught Israel an "unforgettable lesson" with a last-minute missile salvo fired just before a ceasefire deal announced by U.S. President Donald Trump was meant to take effect.

The Guards said in a statement that "in the final moments before the ceasefire was imposed on the enemy", they had struck "military and logistical centers of the Zionist regime across the occupied territories (Israel) with 14 missiles, delivering a historic and unforgettable lesson to the Zionist enemy".

Iran's top security body on Tuesday said the Islamic republic's forces had "compelled" Israel to "unilaterally" cease fire, adding that they remained "on high alert" to respond to "any act of aggression".

Referring to a "divine gift", the Supreme National Security Council said Iran's actions against Israel led to "victory and triumph that compelled the enemy to regret, accept defeat, and unilaterally halt its aggression".

The health ministry said an Israeli strike killed three people Tuesday in the country’s south, the latest such raid despite a November ceasefire.

"The strike launched by an Israeli enemy drone on a vehicle" in the Nabatieh district town of Kfar Dajjal "resulted in the death of three people", the ministry said in a statement carried by the official National News Agency.

Iran announced it had launched missiles at a major U.S. base in Qatar on Monday in retaliation for American strikes on key nuclear facilities, with explosions ringing out in Doha and projectiles seen streaking overhead.

Turkish airline Pegasus has scrapped flights to Iraq, Jordan and Lebanon until June 30, and Iran until July 30, as global airlines suspended or reduced flights in the Middle East amid the Israel-Iran conflict.

Flights of Air France's low-cost carrier Transavia from Paris to Beirut have also been suspended until June 30 while the Tel Aviv route is closed until September 7.

Donald Trump thinks Iranians should overthrow their government if it refuses to negotiate on its nuclear program, but the US president is "still interested" in diplomacy, the White House said Monday.

"If the Iranian regime refuses to come to a peaceful diplomatic solution, which the president is still interested and engaging in, by the way, why shouldn't the Iranian people take away the power of this incredibly violent regime that has been suppressing them for decades?" Press Secretary Karoline Leavitt said on Fox News.

Israel announced strikes on "regime targets" in Tehran on Monday as the longtime foes traded fire for an 11th consecutive day, after Israel ally the United States sent bombers to attack the Islamic republic's nuclear sites.

Here are the latest developments:

Russian President Vladimir Putin on Monday slammed strikes on Tehran as "unprovoked aggression" and said Moscow was trying to help the Iranian people as he hosted Iranian Foreign Minister Abbas Araghchi in Moscow.

"This is an absolutely unprovoked aggression against Iran," Putin told Araghchi, calling the strikes "unjustified" and adding that Russia was "making efforts to provide assistance to the Iranian people."
