As Israel expands its strikes far from Hezbollah’s bastions into areas where displaced Shiites have fled, fears rise about worsening sectarian tensions.

Hezbollah has fired an estimated 13,000 rockets into Israel over the past year in support of Hamas’ war with Israel in Gaza. Tens of thousands of northern Israelis have been displaced from their homes, and Israel has said its escalating war with Hezbollah is aimed at stopping those rockets so families can return home.
