LONDON -- 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.

Hezbollah launched more than 100 rockets early Sunday across northern Israel, with some landing near the city of Haifa, as Israel launched hundreds of strikes on Lebanon. A Hezbollah leader declared an “open-ended battle of reckoning” was underway as both sides appeared to be spiraling closer toward all-out war.
