Israel began bombing Lebanese branches of an association accused of financing the Iran-backed Hezbollah movement, Lebanese state media reported late Sunday, a further escalation of Israel's nearly month-long war against the militants.

Israel's Prime Minister Benjamin Netanyahu on Saturday accused Iran-backed Hezbollah of trying to assassinate him, with the Middle East already on edge after Israel had vowed retaliation for an Iranian missile barrage.

Israel's killing of Hamas leader Yahya Sinwar dealt a huge blow to the Palestinian group, and while it leaves a gaping void at the top of the movement, its militants remain determined to fight.
