US officials believe Israel is focusing on military and energy infrastructure as potential targets in its expected response to an Iranian missile strike earlier this month, NBC News reported Saturday, citing unnamed officials. 

The report suggests Israel has narrowed down its options in retaliation for Iran’s October 1 attack, which followed Israeli military actions in Gaza and Lebanon and the killing of several Hezbollah and Hamas leaders. The missile barrage was Tehran’s second direct retaliation this year, escalating tensions in the region.

While Israel has not made final decisions on the scope or timing of any retaliation, there are no signs that nuclear facilities or assassination operations are being considered, according to the US officials cited by NBC. The response could come during the ongoing Yom Kippur holiday, the report added.

Israeli officials have yet to comment on the NBC report even as the country has vowed to retaliate for the Iranian missile attack, with Defence Minister Yoav Gallant saying the response would be “deadly, precise, and surprising”.

Meanwhile, the clashes between Israel and Hezbollah, which erupted a year ago during the Gaza war, have worsened in recent weeks. The Israeli military continues operations aimed at dismantling Hezbollah infrastructure in southern Lebanon.

“Over the past day, the IAF (air force) has struck approximately 200 Hezbollah targets deep in Lebanon and southern Lebanon, including terrorist cells, launchers, anti-tank missile posts, and terrorist infrastructure sites,” the Israeli military said.
