Israeli warplanes attacked targets near Egypt's borders in the southern Gaza Strip town of Rafah, Palestinian witnesses and security sources said early Wednesday.

Minutes before midnight, F-16 jets dropped a bomb on a smuggling tunnel beneath the borders, used by Palestinians to bring in various goods into the Israeli-blockaded Gaza Strip, witnesses said.

Shortly afterwards, the planes fired three missiles at destroyed installations that once served as Gaza's airport in southeastern Rafah, security sources added.

There was no report on casualties in the two attacks.

On Tuesday night, a home-made rocket fired from Gaza landed in southern Israel, causing no damage. The Israeli attacks in Rafah apparently came in response to the rocket-fire which was claimed by a previously-unknown Islamist Salafi group.
