What we know about the Hezbollah device explosions

At least 32 people, including two children, were killed and thousands more injured, many seriously, after communication devices, some used by the armed group Hezbollah, dramatically exploded across Lebanon on Tuesday and Wednesday.

In the latest round of blasts on Wednesday, exploding walkie-talkies killed 20 and injured at least 450 people, according to Lebanon's health ministry.

The explosions occurred in the vicinity of a large crowd that had gathered for the funerals of four victims of Tuesday's simultaneous pager blasts, which killed at least 12 people and injured nearly 3,000.
