A week before the “Great March of Return” proclaimed by Hamas, four Palestinian infiltrators Saturday night broke through the Gaza-Israel border fence at a point near Kissufim. They poured gasoline and started setting fire to a large IDF crane used in the work of blocking terror tunnels. As soldiers dealt with the damage, the infiltrators were able to escape back into the enclave, leaving behind gasoline and glue containers. The Israeli air force then struck a Hamas target in the Gaza Strip. Last week, the IDF announced army and police preparations for breaking up Palestinian mass demonstrations at the fence which Hamas has scheduled for the coming six weeks.
