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.

Hezbollah’s deadly attack against an Israeli army base presents a major headache for Israel as it continues to struggle to defuse the threat posed by the group.

Lebanese militant group Hezbollah threatened Tuesday to attack targets across Israel and said it would not be defeated by ongoing intense bombardment of its strongholds and leadership.
