The strikes came a day after the United States said it had expressed concerns to Israel about its bombardment of the Lebanese capital. Israel’s military said it had aimed at Hezbollah targets.

Israel’s air force struck targets in Beirut for the first time in almost a week, and the US warned it could cut arms supplies if the humanitarian crisis in Gaza doesn’t improve.

The Pentagon has confirmed it is sending a high-altitude anti-missile system operated by US troops to Israel. Officials say the Terminal High-Altitude Area Defense (Thaad) battery will bolster Israeli air defences after Iran’s missile attack on the country earlier this month.

The advanced THAAD air defense system that the United States is sending to Israel is a sign of how both countries are bracing for more attacks against Israel by Iran and its allies. It adds another layer of protection to the several types of air defense systems that Israel already uses to shoot down missiles.

A single drone, which evaded Israel’s vaunted aerial defense system, slammed into a mess hall at a military training camp deep inside Israel, killing four soldiers and wounding dozens of others

Hezbollah’s deadly attack against an Israeli army base presents a major headache for Israel as it continues to struggle to defuse the threat posed by the group.

Israel said a fresh barrage of missiles was fired from Lebanon a day after a Hezbollah drone strike killed four soldiers, as cross-border fighting between the two sides intensified.
