JERUSALEM (Reuters) -Israel said it was poised to impose quiet on the Lebanese front as hostilities spiked on Sunday, with Hezbollah wounding civilians in a cross-border missile attack and the Israeli air force bombing sites linked to the Iranian-backed group. The chief Israeli military spokesperson, Rear Admiral Daniel Hagari, described Hezbollah as "the defender of Hamas-ISIS", in reference to the Islamist Palestinian faction whose cross-border rampage against Israel on Oct. 7 sparked a devastating Gaza war. Hezbollah, whose rocket arsenal is widely believed to dwarf that of Hamas, has been carrying out relatively limited attacks in solidarity with the Palestinians.
