Just one day after pagers used by hundreds of members of the militant group Hezbollah exploded, more electronic devices detonated in Lebanon on Wednesday in what appeared to be a second wave of sophisticated, deadly attacks that targeted a lare number of people.

Both attacks, which are widely believed to be carried out by Israel, have hiked fears that the two sides’ simmering conflict could escalate into all-out war.
