Israel launched a series of strikes on Hezbollah targets Thursday as the war against the Lebanon-based group widened in the wake of two consecutive days of deadly explosions triggered in wireless devices.

Thousands of people were injured Tuesday and several killed when their pagers exploded almost simultaneously across Lebanon, officials said, with Hezbollah confirming some of its members were wounded and blaming the attack on Israel.

Israel launched a series of overnight strikes on sites in Lebanon where the Israeli military says Hezbollah terrorists operated. The strikes follow two waves of deadly electronic device explosions across Lebanon.
