Israel launched fresh strikes on Beirut's southern suburbs late Sunday as Israel's military said it was striking Hezbollah infrastructure in the city following earlier raids mainly in the country's south.

A midnight strike, heard in the capital, came after a morning Israel army evacuation warning for Beirut's southern suburbs, which Israel has repeatedly struck in the past fortnight.

The Israeli military said on Monday it had begun what it described as "limited ground operations" against Hezbollah in southern Lebanon.

Lebanon was drawn into the Middle East war on March 2 when the Tehran-backed Hezbollah attacked Israel in response to the killing of Iranian supreme leader Ayatollah Ali Khamenei in U.S.-Israeli strikes, with Israel launching air raids on the neighboring country and troop incursions into border areas.

Israel said on Sunday that no direct talks were planned with Lebanon to end the war, a day after a Lebanese official said Beirut was preparing a delegation to negotiate with Israel.

Overnight strikes in southern Lebanon killed at least four people, Lebanese state media and the government said on Sunday, as Israel said it was pressing its campaign against Iran-backed Hezbollah.

Here are the latest events in the Middle East war:

Donald Trump warned that he is not ready to seek a deal to end the war with Iran, as U.S. ally Israel launched a new wave of strikes Sunday and Tehran's Revolutionary Guards threatened to hunt down and kill the Israeli leader.

Israel has approved an $827-million emergency budget allocation for military purchases, Israeli media reported Sunday, as the war with Iran entered its third week.

Hezbollah said it was involved in "direct clashes" with Israeli forces in the southern Lebanese town of Khiam late on Saturday.

In a statement, it said the clashes were ongoing, having started at 9:20 pm (1920 GMT) and involved "light and medium weapons as well as rocket-propelled projectiles".

U.S. President Donald Trump urged other nations to help secure a vital shipping lane choked off by the war with Iran that showed no signs of slowing on Saturday as strikes hit the U.S. embassy in Baghdad and a major Emirati energy facility.

France's foreign ministry said Saturday there was "no French plan" to stop the fighting in Lebanon between Israeli forces and Iran-backed militant group Hezbollah.
