BEIRUT (Reuters) - Reuters journalists in Beirut's southern suburbs heard at least two contained blasts in separate parts of the suburbs on Wednesday.

It was not immediately clear what had caused the explosions but they came a day after pagers used by armed group Hezbollah detonated across Lebanon.
