Cairo–At least one Egyptian policeman was injured when unknown attackers fired four rocket-propelled grenades at a police barracks in the Gaza border town of Rafah on Monday, a security source said.
It was not immediately clear who was behind the attack or whether it was linked to the protests against the 30-year-old autocratic regime of President Hosni Mubarak that are raging around Egypt.
A Coptic church in Rafah, which border the Gaza Strip, caught fire on Saturday, with some witnesses saying there had been an explosion.
Saboteurs attacked a gas pipeline to Jordan in the same area on the same day forcing authorities to switch off supplies from a twin pipeline to Israel.
An armed Bedouin group in June threatened to attack the pipeline, security officials said, leading Egyptian authorities to beef up security around the pipeline and terminal.
Police relations with the region's former nomads are often tense, with the Bedouin complaining of routine harassment and discrimination.
Human rights groups have criticised Egyptian policy towards the Bedouin, who faced harsh police treatment after a series of bombings in Sinai resorts between 2004 and 2006, which killed dozens of Egyptians and foreign tourists.
