The Israeli military apologized Monday for a strike that killed three Lebanese soldiers in southern Lebanon, saying it is not battling the country's military and its troops believed they were targeting a vehicle belonging to the Hezbollah militant group.

Israeli strikes meanwhile hit nearly a dozen branches of a Hezbollah-run financial institution that Israel says is used to fund attacks but where many ordinary people keep their savings.

Last week, Hezbollah said it is entering a new phase in its fight against invading Israeli troops, as the region reckoned with the killing of top Hamas leader Yahya Sinwar in a battle with Israeli forces in Gaza. Sinwar was a chief architect of the attack on southern Israel that precipitated the latest escalating conflicts in the Middle East.

Israeli Prime Minister Benjamin Netanyahu has pledged to annihilate Hamas and recover dozens of hostages held by the group. Hamas says it will only release the captives in return for a lasting cease-fire, a full Israeli withdrawal from Gaza and the release of Palestinian prisoners.
