Ceasefires have been announced, often to great fanfare, in Gaza, Lebanon and Iran. So why is there still so much fighting?

In just the last few weeks, Israeli forces have captured more territory in Gaza and killed two top Hamas militants there, as well as more than a dozen other people. In Lebanon, Israeli troops captured a Crusader fortress over the weekend in their deepest incursion in 26 years, as Hezbollah kept up rocket fire into northern Israel.

Israel has portrayed the capture of a Crusader-era fortress as a turning point in its offensive against Hezbollah, but the operation has also sparked fears of a new quagmire in south Lebanon.

Israeli authorities praised the symbolism of the capture of Beaufort, perched atop a rocky outcrop, as they announced its capture in an assault documented by military drones.

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.

Lebanon is seeking an international force to replace a decades-long United Nations peacekeeping mission whose mandate ends this year following U.S. and Israeli pressure, even as the latest Israel-Hezbollah war continues.

The U.S. announced unprecedented sanctions on two Lebanese officers on Thursday, accusing them of sharing intelligence with Hezbollah, which the Lebanese government is trying to disarm.

On the surface, Chinese leader Xi Jinping's back-to-back summits with U.S. President Donald Trump and Russia's Vladimir Putin looked pretty similar, with formal handshakes in Beijing's Tiananmen Square, enthusiastic greetings from flower-waving children, and marching columns of soldiers with gleaming bayonets. But the visits also revealed how different China's relationship is with the two countries.

During Trump's visit, China sought to stabilize ties with the United States, while Putin's trip served to deepen its strategic partnership with Russia.

Lebanon's Simon Karam and Israel's Yechiel Leiter, both political veterans with entrenched views, will come face to face in Washington for talks Thursday after decades in a state of war.

Lebanon and Israel have no formal ties, but U.S. President Donald Trump is hoping for a historic breakthrough even as Israeli forces remain deployed in south Lebanon to fight Iran-backed Hezbollah.

Hours after the UAE's top oil executive said the country had "emerged stronger" from war and as thousands attended an Abu Dhabi summit to boost the local economy, phones across the country were alerting that missiles were incoming.

The first attacks since a truce came into effect last month were a stark reminder of its fragility, dampening hopes of a quick return to normality, with Iran imposing a new reality: should the United States or Israel strike, the UAE would be the one to pay.

The ongoing war between Israel and Hezbollah is far from the first conflict between them. The two have an enmity that goes back more than four decades, with outbursts of fighting or outright war punctuated by periods of tense calm.

Here is a timeline of some significant events in the hostilities between the two:

The former Lebanese president who once signed a short-lived deal with Israel ending decades of a state of war now says the time is right to try again.

Amin Gemayel spoke with The Associated Press in an interview Wednesday after the first direct talks between Lebanon and Israel since the 1980s, as they explore what could lead to a security agreement or even the eventual normalization of relations. He is part of one of Lebanon's strongest political dynasties that founded the Christian Kataeb Party, which held powerful positions for decades.
