The Christian quarter in south Lebanon's Tyre, the last pocket of the coastal city spared from Israeli threats, was emptied out on Tuesday after an unprecedented warning for the city's residents.

The Israeli army on Tuesday said its forces killed a gunman who had managed to infiltrate Israeli territory from Lebanon and opened fire on its troops.

France Tuesday banned far-right Israeli Finance Minister Bezalel Smotrich from entering the country, the French foreign minister said, slamming him for actively promoting the annexation of the West Bank and the "re-colonization" of Gaza.

"Four leaders of settler organizations, and twenty-one violent settlers" were also banned from French territory, Jean-Noel Barrot wrote on X, condemning a "policy that the overwhelming majority of the international community, firmly committed to the two-state solution, cannot accept".

An Israeli airstrike on the southern city of Tyre before an Israeli military warning on Tuesday killed at least eight people and wounded 32 others.

The state-run National News Agency (NNA) had reported the strike not long before Israel's military issued an evacuation warning for the entire city and surrounding areas ahead of strikes there.

Hezbollah on Tuesday urged Lebanese authorities to mend their relationship with the group's backer Iran and benefit from Tehran's support, days after Iran struck Israel in response to bombardment on south Beirut.

Last week Lebanon's president and prime minister issued pointed calls for Tehran to stop interfering in their country's affairs, after Hezbollah rejected a conditional ceasefire with Israel.

The enormous costs of Israel's multi-front war and Prime Minister Benjamin Netanyahu's determination to turn his country into a "super-Sparta" of the Middle East are driving up the defense budget and raising fears of cutbacks in education and healthcare.

The total cost of the series of interconnected regional conflicts that began with Hamas's attack on Israel on October 7, 2023 stood at 405 billion shekels ($138 billion) as of late April, according to the governor of the Bank of Israel, Amir Yaron.

The heads of the Pakistani and Lebanese armed forces agreed to boost cooperation on Tuesday as they met in Pakistan with peace talks over the Middle East war dragging on.

Pakistan has been mediating between the United States and Iran to end the months-long conflict, with Tehran insisting that any deal should include Lebanon.

Israeli Defense Minister Israel Katz has vowed to press on with Israel's military campaign in Lebanon, despite a warning from Iran that any such action would prompt the Islamic republic to take "severe" measures in response.

"The IDF will continue to operate in Lebanon against the terrorist organization Hezbollah," Katz said in a statement Monday, adding that Israel would strike Beirut's southern suburbs, known as Dahieh, in retaliation for every attack on northern Israel.

The Israeli army ordered Tuesday residents of the historic city of Tyre and its suburbs, including the city's Christian neighborhood, to evacuate ahead of expected strikes.

"Urgent warning to the residents of the city of Tyre, including the Christian quarter, and the camps and surrounding neighborhoods," read a message posted on X by the Israeli military's Arabic-language spokesman Avichay Adraee.

Iranian President Masoud Pezeshkian on Monday said Tehran remained at the negotiating table after halting attacks on Israel following the first exchange of fire since the April truce.

"Diplomacy and defense are the two wings of national power; we have neither left the battlefield nor the negotiating table," Pezeshkian said in a post on X, adding that Tehran "will not retreat in the face of any threat".
