How did the Hezbollah pager explode and who was behind it?

Pagers used by Hezbollah, Lebanese officials and several Iranian diplomats exploded in a series of explosions Tuesday across parts of Lebanon, killing at least nine people and injuring more than 2,750. Analysts were shocked by what happened and came up with several hypotheses about what could have caused the pager to explode, some of which were very likely and some were not. Lebanon and Hezbollah blame Israel for the blast, while Israel remains silent. แทงบอลยูโร
