CAIRO (AP) — This week saw a dizzying escalation in the 11-month-old conflict between Israel and Lebanon’s Hezbollah. First came two days of exploding pagers and walkie-talkies used by Hezbollah — deadly attacks pinned on Israel that also maimed civilians around Lebanon.

Israel is attempting a risky strategy, increasing the intensity of its attacks in an attempt to force Hezbollah to back down, while raising the chances of an aggressive response that devolves into a land war.

Hezbollah launched a barrage of 140 rockets into northern Israel on Friday, a day after its leader, Hassan Nasrallah, vowed revenge for a massive Israeli bombing, according to statements from both the Israeli military and Hezbollah.
