Israeli jets launched a series of air strikes Sunday night against several targets in the Gaza Strip, including an empty Hamas police station and the border between Gaza and Egypt, DPA quoted witnesses as saying. Residents of the southern Gaza Strip town of Rafah, which borders Egypt, said that Israeli F-16 warplanes dropped at least four large bombs at the border area. No injuries were reported. Rafah resident Ahmed al-Sha'er said that warplanes had been flying over Rafah, bombing with the apparent aim of destroying underground tunnels. Al-Sha'er said that he saw dozens of families leaving their homes Sunday evening and moving to safer places in the northern area of Rafah, after receiving Arabic warning messages from Israel. Witnesses had earlier said that Israeli aircraft twice struck an empty police post of the Hamas movement in central Gaza Strip. No injuries were reported. They told local radio stations that F-16s had been circling over the central area of the enclave and fired a missile into the Hamas police post, which was completely destroyed. No injuries were reported.
