Israeli warplanes early Monday bombed one of the smuggling tunnels on the border between the Gaza Strip and Egypt, witnesses and local sources said.

The sources said F-16 fighter jets fired at least two missiles targeting a tunnel in the Jeradat crossing east of Rafah in the southern Gaza Strip.

No casualties were reported in the raid.

The Israeli Defense Force has not confirmed Monday's strikes.

The Israeli Air Force has been conducting regular raids on these tunnels, which Israel says were being used by Palestinian armed factions to smuggle weapons into the Hamas-controlled Gaza Strip.

The latest Israeli raid came after a rocket fired by militants Saturday from the Gaza Strip fell on empty land south of Ashkelon in southern Israel, causing no casualties or damage.

The Israeli military vowed to continue responding to Palestinian attacks.
