U.S. officials believe Israel has narrowed down what they will target in their response to Iran’s attack, which these officials describe as Iranian military and energy infrastructure.

Israel stepped up airstrikes aimed at Hezbollah in Lebanon while continuing to deliberate how to retaliate against Iran for last week’s missile attack.

Humanitarian laws of war, including the Geneva Conventions, require military forces to give civilians ample warning to flee before attacking. Israel has issued evacuation alerts for large sections of south Lebanon, though, in some cases, it has given people as little as two hours to leave their homes before striking.

Israel’s ground operation in Lebanon stretched into its second week, as the Hezbollah militant group continued to fire hundreds of rockets deep into Israel.

Hezbollah critics and supporters alike are voicing frustration over what many view as the group's miscalculations.
