By Alistair Bunkall, Middle East correspondentThe day after the attack, there are still more questions than answers: how did Israel tamper with the pagers, how were the devices remotely detonated, and, most importantly as we look forward, why now?Israel has clearly penetrated deep inside Hezbollah. This attack would have taken at least months to plan and prepare, and considerably technological skill to pull it off.
For now, still only a few hours after the attack, that probably remains the most likely explanation, however I would have expected some activity from the IDF overnight – widespread airstrikes or movement from ground forces. This would have had the effect of exploiting Hezbollah whilst it's still reeling and pushing home the advantage gained from the pager attack.Israeli intelligence will be using these hours to hoover up a mine of invaluable data and information in the aftermath.
