Pakistan’s foreign minister says Islamabad soon will host talks between the U.S. and Iran.

Foreign Minister Ishaq Dar made the announcement Sunday. He did not specify whether the talks would be direct or indirect. There was no immediate word from the U.S. or Iran.

“Pakistan is very happy that both Iran and the U.S. have expressed their confidence in Pakistan’s facilitation” of the talks, which will happen in the “coming days,” Dar said in a televised speech after top diplomats from regional countries met in Islamabad.

He said the foreign ministers of Turkey, Egypt and Saudi Arabia endorsed Pakistan’s peace efforts. The ministers are expected to meet again Monday.

Pakistan has emerged as a mediator, having relatively good ties with both Washington and Tehran. Pakistani officials have said their public effort follows weeks of quiet diplomacy.

THIS IS A BREAKING NEWS UPDATE. AP’s earlier story follows below.

ISLAMABAD, Pakistan (AP) — A top Iranian official warned the U.S. against a ground invasion, saying its troops would be set “on fire,” as regional diplomats met Sunday in Pakistan in hopes of opening direct U.S.-Iran talks and ending the monthlong war.

Israeli Prime Minister Benjamin Netanyahu said Israel will widen its invasion of Lebanon, expanding the “existing security strip” in that country's south while targeting the Iranian-backed Hezbollah militant group. There were no details.

Iran’s parliament speaker, Mohammad Bagher Qalibaf, dismissed the talks in Pakistan as a cover after some 2,500 U.S. Marines trained in amphibious landings arrived in the Middle East. He said Iranian forces were “waiting for the arrival of American troops on the ground to set them on fire and punish their regional partners forever,” according to state media.

The war has threatened global supplies of oil, natural gas and fertilizer and disrupted air travel. Iran’s grip on the strategic Strait of Hormuz has shaken markets and prices, and now the Iranian-backed Houthi rebels ' entry into the war could threaten shipping on another crucial waterway, the Bab el-Mandeb strait to the Red Sea.

“We don’t know at what moment our homes could be targeted,” said Razzak Saghir al-Mousawi, 71, describing relentless airstrikes as Iranians crossing into Iraq urged the United States to end the war. “I am definitely afraid.”

More than 3,000 people have been killed in the war that began with U.S. and Israeli strikes on Iran that triggered Iranian attacks on Israel and neighboring Gulf Arab states. The war continues on the digital front as well.

Pakistan said the foreign ministers of Saudi Arabia, Turkey and Egypt met in Islamabad without U.S. or Israeli participation, days after the U.S. offered Iran a 15-point “action list” as a framework for a possible peace deal. The ministers are expected to meet again Monday.

Egypt’s Badr Abdelatty said the meetings are aimed at opening a “direct dialogue” between the U.S. and Iran, which have largely communicated through mediators. Both this war and last year's 12-day war began during rounds of indirect talks.

Iranian officials have rejected the U.S. framework and publicly dismissed the idea of negotiating under pressure. But Press TV, the English-language arm of Iran’s state broadcaster, reported last week that Tehran had drafted its own five-point proposal that reportedly called for a halt to killing Iranian officials, guarantees against future attacks, reparations and Iran’s “exercise of sovereignty over the Strait of Hormuz.”

Iran has eased some restrictions on commercial ships in the strait, agreeing late Saturday to allow 20 more Pakistani-flagged vessels to pass through. It "sends a clear signal that Iran remains open for business with the world, provided the United States abandons coercion,” said Asif Durrani, Pakistan’s former ambassador to Iran.

An adviser to the United Arab Emirates, Anwar Gargash, called for any settlement to the war to include “clear guarantees” that Iranian attacks on neighbors will not be repeated.

Gargash said Iran's government has become “the main threat” to Persian Gulf security and called for compensation for attacks on civilian infrastructure.

Iran on Sunday warned of escalation after Israeli airstrikes hit several universities, including ones that Israel claimed were used for nuclear research and development. Concerns over Iran's nuclear program are at the heart of tensions.

The paramilitary Revolutionary Guard warned that Iran would consider Israeli universities and branches of U.S. universities in the region “legitimate targets” unless offered safety assurances for Iranian universities, state media reported.

U.S. colleges have campuses in Qatar and the UAE, including Georgetown, New York and Northwestern universities.

“If the U.S. government wants its universities in the region spared, it should condemn the bombardment" of Iranian universities by midday Monday, the Guard said in a statement.

Iranian Foreign Ministry spokesperson Esmaeil Baqaei said Saturday that dozens of universities and research centers have been hit, among them the Iran University of Science and Technology and Isfahan University of Technology.

Both sides in the war have threatened to attack civilian facilities, which critics have warned could be a war crime.

In Lebanon, officials said more than 1,200 people have been killed. There were fears of more deaths after Netanyahu, speaking on a visit to northern Israel, said Israel was “determined to fundamentally change the situation in the north.” He said Hezbollah “still has residual capability to fire rockets at us.”

Iranian authorities say more than 1,900 people have been killed in the Islamic Republic, while 19 have been reported dead in Israel.

In Iraq, where Iranian-supported militia groups have entered the conflict, 80 members of the security forces have died.

In Gulf states, 20 people have been killed. Four have been killed in the occupied West Bank.
