Rocket fire heats up between Israel and Hezbollah

Israel (MNN) -- After 11 months of tit-for-tat rocket fire, tensions between Israel and Hezbollah are building into something more. On Monday and Tuesday, Israeli airstrikes in Lebanon killed more than 500 people. Hezbollah has fired rockets back at Israel, with no immediate casualties reported.  This escalation comes nearly a week after communications devices used by Hezbollah exploded in Lebanon, killing more than 30 and wounding thousands.
