Egypt has bolstered security along the border in order to keep weapons and explosives from being smuggled into the Gaza Strip.
Officers patrolling the border between the Gaza Strip and Sinai found anti-aircraft missiles, a quarter ton of TNT, and other weaponry hidden in villages and cemeteries near Rafah, the source said.
The increased patrols, which began Monday, also succeeded in uncovering two large tunnels used for smuggling cars from Egypt into Gaza near Rafah.
Egypt says it will continue the patrols over the next few days. So far, no arrests have been made.
Last week Egyptian security forces found five weapons caches that had been prepared for smuggling into Gaza. Palestinian reports said the troves included 100 anti-aircraft missiles and 100 kg of TNT.
