Gaza-based Palestinian terrorists expanded their rocket offensive to include Egypt on Wednesday when they fired a short-range Kassam into the Sinai border town of Rafah.
An Egyptian woman was wounded when the rocket hit a residential neighborhood on the Egyptian side of Rafah, which is split by the Sinai-Gaza border.
Egyptian security officials expressed "concern" over what appeared to be a new phenomenon of Palestinian terrorist aggression against Egypt.
Presumably, whoever fired the rocket is angry over Egypt's cooperation with Israel in hunting down those responsible for last week's three-pronged terrorist assault near the Israeli resort town of Eilat.
Palestinian terrorists from Gaza had used the Egyptian Sinai to infiltrate the southern tip of Israel before killing eight Israelis and wounding many more.
Since then, Egypt has tightened security along the border and launched a widespread effort to reassert its control over the increasingly lawless Sinai.
Another part of that effort is ending attacks by Islamists on the Sinai pipeline that transfers Egyptian natural gas to neighboring Israel and Jordan. The pipeline has been blown up by local militants six times since the February ouster of former Egyptian dictator Hosni Mubarak.
As regards Gaza and the Palestinians, Egyptian newspaper Al-Shorouk reported on Wednesday that in order to minimize the ability of terrorists to enter the Sinai, Egyptian security forces are planning to destroy the network of tunnels that run under the Gaza-Sinai border.
Those tunnels have been used for years to smuggle everything from luxury items to outlawed weapons into Gaza.
