US Defense Secretary Pete Hegseth said Thursday there is no "time frame" for ending the US-Israeli war against Iran, which was launched three weeks ago.

The line of cars stretched as far as the eye could see along the coast of southern Lebanon, as residents of areas bombarded in the Israel-Hezbollah war poured into the ancient city of Sidon in search of safety.

In southern Lebanon's Ain Ebel, close to the border with Israel, Suad Jallad holds a poster of her son, killed by Israel last week, saying she would rather be buried next to him than leave.

After being forced to flee with his family from Israeli air raids on southern Lebanon, Hussein Fakih searched in vain for an apartment, amid strict measures imposed by hotels and landlords afraid that guests might be targeted by Israel.

Hezbollah suffered heavy losses in a war with Israel more than a year ago, but the Iran-backed group has now regrouped only to end up fighting what it has called an "existential battle" and which some warn could be its last.

Lebanon was drawn into the Middle East war last week when the militant group, funded and armed by Iran, attacked Israel in response to the killing of Iran's supreme leader Ayatollah Ali Khamenei in U.S.-Israeli strikes.

When an air strike hit their Beirut neighborhood, people were angry with Israel, but they reserved their deepest rage for Hezbollah, for dragging Lebanon into the Middle East war.

Israel and the United States launched huge strikes on Iran on February 28, killing its supreme leader and sparking a massive retaliatory campaign.

The Lebanese mother of two had just awakened to prepare the pre-dawn meal before another day of fasting during the Muslim holy month of Ramadan when Israeli warplanes began attacking southern Lebanon in retaliation for rockets and drones launched by Hezbollah.

The family quickly packed up and headed toward Beirut, seeking safety from another deadly war between Israel and Hezbollah. With tens of thousands of others fleeing on that March 2 day, the usually one-hour trip from the southern city of Nabatiyeh took 15 hours.

Engaged in a new war with Hezbollah, the Israeli army announced this week its intention to establish a buffer zone in southern Lebanon while its forces began advancing into border towns.

What is the purpose of creating this buffer zone and what risks does it pose?

As U.S. forces mass in the Middle East, Iran faces the threat of major strikes by the world's most powerful military, potentially targeting its leaders, military, nuclear sites and critical infrastructure.

Iran has nowhere near the same capabilities, and is even more vulnerable after last year's war launched by Israel and recent anti-government protests. But it could still inflict pain on American forces and allies, and may feel it has to if the Islamic Republic's survival is at stake.

What began as an ordinary shift for Jerusalem bus driver Fakhri Khatib ended hours later in tragedy.

A chaotic spiral of events, symptomatic of a surge in racist violence targeting Arab bus drivers in Israel, led to the death of a teenager, Khatib's arrest and calls for him to be charged with aggravated murder.
