Preparations are being made to open a second front against Israel from Gaza when the next round of the war with Hezbollah (and possibly Syria) breaks out:
According to official sources in Jerusalem, some 100 Hamas terrorists crossed the Rafah border terminal in recent weeks. Intelligence information collected by the defense establishment indicates that the terrorists make their way to special training camps in Iran and Syria, founded specially to train and coach Palestinians for terror attacks against Israel should Hamas decide to terminate its ceasefire.
Security officials in Israel said this phenomenon was part of the recent trend by which Iran and Syria have shown increasing involvement in developing Palestinian terror infrastructure in the Gaza Strip. — YNet
