Lebanon is rocked again by exploding devices as Israel declares a new phase of war. Walkie-talkies and solar equipment exploded in Beirut and other parts of Lebanon on Wednesday in an apparent second wave of attacks targeting devices a day after pagers used by Hezbollah blew up, state media and officials for the militant group said. At least 20 people were killed and more than 450 wounded in the second wave, the Health Ministry said. The attacks - which were widely believed to be carried out by Israel targeting Hezbollah but have also killed civilians - have hiked fears that the two sides' simmering conflict could escalate into all-out war.
