Hezbollah, which has exchanged fire with Israeli forces since October, last went to war with Israel in 2006 and has since expanded its domestic and regional influence, politically and militarily.

Financed and armed by Iran, Hezbollah is the most prominent actor in the so-called axis of resistance -- regional pro-Tehran armed groups opposed to Israel that also include Palestinian militants Hamas, Iraqi movements and Yemen's Houthi rebels.

Israel and Hezbollah on Sunday launched their heaviest exchange of fire after months of strikes and counterstrikes, raising fears of an all-out war that could potentially draw in the United States, Iran and militant groups across the region.

By mid-morning, it appeared the exchange of fire had ended, with both sides saying they had only aimed at military targets. Lebanese authorities said the Israeli strikes killed three people, while there were no reports of casualties on the Israeli side. The situation remained tense.

Hezbollah has provided a glimpse of its secret tunnels housing weapons -- a move experts say is a warning to Israel as the underground facilities could prove vital to the group should wider war erupt.

The Iran-backed movement has exchanged regular fire with Israel in support of its ally Hamas since the Palestinian militant group's October 7 attack on Israel sparked the Gaza war.

Hopes were dwindling Thursday for a ceasefire in the Gaza Strip, where fighting raged despite pressure from the United States on Israel and Palestinian militants Hamas to reach an agreement.

After more than 10 months of war, officials from the United States and Arab mediators Egypt and Qatar had been set to meet in Cairo for a new round of talks this week, but confirmation was still pending.

Israel's demand for lasting control over two strategic corridors in Gaza, which Hamas has long rejected, threatens to unravel cease-fire talks aimed at ending the 10-month-old war, freeing scores of hostages and preventing an even wider conflict.

Officials close to the negotiations have said Israel wants to maintain a military presence in a narrow buffer zone along the Gaza-Egypt border it calls the Philadelphi corridor and in an area it carved out that cuts off northern Gaza from the south, known as the Netzarim corridor.

Hezbollah has gradually revealed its military capabilities in 10 months of cross-border clashes with Israel, analysts say, including footage of underground missile facilities released Friday amid fears of all-out war.

A daring Ukrainian military push into Russia's Kursk region has seen Kyiv's forces seize scores of villages, take hundreds of prisoners and force the evacuation of tens of thousands of civilians in what has become the largest attack on the country since World War II.

In more than a week of fighting, Russian troops are still struggling to drive out the invaders.

Iran's threatened retaliatory strike on Israel over the assassination of Hamas official Ismail Haniyeh drew major world powers on Tuesday into a high-wire act of diplomacy.

Halting or limiting an Iranian strike in some eyes could bolster a monthslong effort to reach a cease-fire in a war that's devastated the Gaza Strip and killed nearly 40,000 Palestinians, according to the territory's health ministry. It could also free the Israeli hostages who remain captive there since Hamas' Oct. 7 attack on southern Israel.

Hezbollah launched one of its deepest strikes into Israel in mid-May, using an explosive drone that scored a direct hit on one of Israel's most significant air force surveillance systems.

This and other successful drone attacks have given the Iranian-backed group another deadly option for an expected retaliation against Israel for its airstrike in Beirut's southern suburbs last month that killed top Hezbollah military commander Fouad Shukur.
