Russia launched hundreds of drones and dozens of missiles against Kyiv and other Ukrainian cities overnight, killing at least 14 civilians and wounding more than 100 others, authorities said Tuesday.

Some people were trapped under the rubble of apartment buildings, including a 3-year-old child whose body was pulled out by emergency crews in the central Ukrainian city of Dnipro, officials said, as the attack stretched from night into day and the boom of explosions reverberated across cities.

A strike on a car on the Khardali road in south Lebanon killed a man, his son and his daughter, who were students, as he drove them back from university exams in Beirut to the southern border village Qlayaa, where some residents were still holding out despite Israeli evacuation orders.

Theodosia Karam, the daughter, had exams at the Lebanese University in Hadath and left with her father and 12-year-old brother after Israel threatened Beirut's southern suburbs. They drove to their hometown, Qlayaa.

The United Nations on Monday expressed its alarm and called for all sides to respect the ceasefire as Israel expanded its offensive into Lebanon, while negotiations to end the U.S.-Iran war appeared in peril.

"We are deeply alarmed by the escalation in military activities across southern Lebanon and beyond," Stephane Dujarric, spokesman for U.N. Secretary-General Antonio Guterres, said.

Israeli forces are making their deepest incursion inside Lebanon since they withdrew from the country over a quarter-century ago, despite a nominal U.S.-brokered ceasefire and the first direct talks between the countries in decades.

The Israeli advance presents a challenge in the emerging deal to extend the Iran war ceasefire as Tehran wants any agreement to end fighting in Lebanon, too. Qatar called it a "dangerous escalation." Germany's foreign minister said it was cause for serious concern, according to German press agency dpa. There was no comment by the United States.

Israeli troops have captured a strategic mountain topped with a Crusader-built castle in southern Lebanon in the deepest incursion into the country in more than a quarter-century, the military said Sunday, while U.S. Secretary of State spoke to Lebanese and Israeli leaders in an effort to keep negotiations going.

U.S. Secretary of State Marco Rubio spoke to Lebanese President Joseph Aoun and Israeli Prime Minister Benjamin Netanyahu to propose a fresh path to continue ongoing negotiations, according to a U.S. official who spoke on condition of anonymity to discuss private diplomatic conversations. Under the proposal, Hezbollah would halt all attacks on Israel and Israel would refrain from escalating military operations in the Lebanese capital of Beirut, according to the official.

Israel's government ordered strikes on the southern suburbs of Beirut on Monday, a day after its ground forces reached their deepest point in Lebanon in 26 years and as Hezbollah fired rockets at northern Israel including the outskirts of coastal city of Haifa.

A joint statement by Israeli Prime Minister Benjamin Netanyahu and Defense Minister Israel Katz said that following what they called repeated violations of the ceasefire by Hezbollah and the "attacks against our cities and citizens," they have ordered the Israeli military to attack targets in Beirut's southern suburbs known in Arabic as Dahieh.

Israeli Prime Minister Benjamin Netanyahu on Sunday said he ordered the Israeli army to deepen its deployment in Hezbollah strongholds north of the Litani River, noting that "soon Hezbollah will no longer have the ability to threaten northern Israel."

Israel's flag flew over the medieval fortress on Beaufort in Lebanon on Sunday as it warned Lebanese civilians to evacuate a large area of the south of the country ahead of stepped up ground operations.

Shelling was audible and smoke rose from the surrounding area as the invading army's banner was seen by AFP above the castle, which Israeli forces famously used as a base during their previous two-decade long occupation.

The Trump administration has extended protections shielding about 11,000 Lebanese from deportation, allowing them to stay and work in the United States for another six months.

The decision, announced Thursday by the Department of Homeland Security, marked a rare reprieve for people protected by temporary measures which have been harshly criticized by Republicans. The extension comes amid ongoing fighting in southern Lebanon between Israeli troops and Hezbollah fighters.

Hezbollah has again rejected direct talks between Lebanon and Israel on the eve of military negotiations between the two sides.
