Israel has decimated Hezbollah’s leadership with strikes over the past week, while also killing hundreds of civilians and forcing nearly 1 million people from their homes.

Hezbollah’s longtime leader, Hassan Nasrallah, was taken out in an Israeli attack Friday on Hezbollah’s central headquarters in Beirut. The United States has said justice was served to Nasrallah, a key Iranian ally in the region.

However, Washington is also urging a diplomatic solution to a conflict that is moving ever-closer to an all-out war, especially as Israel threatens a ground invasion.

Israel expanded its air strikes across Lebanon over the weekend, hitting central Beirut on Monday for the first time in months. Local officials say more than 1,000 civilians have been killed across Lebanon over the past week, including 100 on Sunday.

“There's no safe place guaranteed in Lebanon,” Jihan Kaisi, the head of a group helping displaced people, told NBC News.

Here are five pressing questions about the conflict.

Will Israel launch ground invasion?

Multiple outlets reported on Monday that Israel has informed the United States of plans to launch a limited ground incursion into Lebanon as soon as Monday.

The Washington Post reported that Israeli forces carried out limited raids across the border on Monday. Hezbollah’s elite Radwan force is believed to be hiding in tunnels close to the border.

“The Radwan force, no matter how many times we attack, you cannot destroy that from the air,” Miri Eisin, a former senior Israeli military intelligence officer, told the Post. “To be able to get to that subterranean arena, which is 2-3 kilometers from Israel’s border, you have to go in.”

U.S. officials say they have been told that Israel will not conduct a full-scale invasion.

“They have at this time told us that those are limited operations focused on Hezbollah infrastructure near the border, but we're in continuous conversations with them about it,” State Department Spokesman Matthew Miller said in Monday's briefing.

Israel has repeatedly threatened to send troops into Lebanon to push back the threat of attacks on northern Israel, with its top commander telling troops this week and last to prepare for a ground invasion.
