Israel's defense minister said on Sunday the country was ready to handle any scenario that may develop with its foe Iran as it stayed on alert for a possible retaliatory attack to the killing of Iranian generals on April 1.

Defense Minister Yoav Gallant's office made the statement after he held an "operational situation assessment" with senior military officers.

"Upon completing the assessment, Minister Gallant emphasized that the defense establishment has completed preparations for responses in the event of any scenario that may develop vis-à-vis Iran," his office said.

An Israeli precision strike on the Iranian embassy compound on April 1, killed two top IRGC Quds Force generals and seven other officers, rattling the Iranian government that has vowed to punish Israel.

Meanwhile, Israel launched air strikes on eastern Lebanon early on Sunday, hitting what it said were Hezbollah infrastructure sites after the armed group downed an Israeli drone over the country as both sides continue to trade fire amid escalating regional tensions.

The Israeli army said in a statement that fighter jets struck a military complex and three other infrastructure sites belonging to Hezbollah in the eastern city of Baalbek.

It said the latest attack was in response to Iran-backed Hezbollah's downing of an unmanned aerial vehicle in Lebanese airspace, which the group identified as the Israeli-made Hermes 900 drone.

Hezbollah has been trading fire with Israel across Lebanon's southern border since October 8, a day after the Palestinian group Hamas launched an attack on Israel that sparked Israel's war in Gaza and led to escalating regional tensions.
