Col. Ahmed Mohammed Ali, a spokesman for Egypt's armed forces said, “the armed forces managed to stop two cars, a Toyota Doble Cabina and a Daewoo Lanos with no plates, in an area between Rafah church and a military unit under construction.”
The military spokesman added that one of the vehicles carrying “masked elements” was able to escape. He said weapons seized in the other vehicle included sacks of TNT, two automatic weapon, 50 rounds, five electric detonators and an RPG launcher.
Earlier, Egypt’s official MEAN news agency reported that “army units foiled an attack against the Rafah church at 1:00 am (2300 GMT Sunday) and seized a car packed with explosives and weapons near the church.”
Egypt's Coptic minority celebrates Monday its first Christmas under Islamist rule and amid a climate of fear and uncertainty for their future, although President Mohamed Mursi has pledged to be the “president of all Egyptians.”
In September, residents and officials reported that several Coptic families from Rafah had fled from the Sinai peninsula town that borders the Gaza Strip after receiving death threats from Islamists.
Egyptian security sources suggested, meanwhile, that the planned attack could have been aimed at a military camp under construction near the church which has been targeted in the past by Islamist militants.
They said the church has been lying abandoned for the past two years after it was torched in the aftermath of the countrywide uprising that toppled the regime of former president Hosni Mubarak in February 2011.
It was not immediately clear who was behind the planned attack but one security source said the perpetrators were “probably radical Islamists whom security forces have been tracking for months.”
Mursi, who hails from the powerful Muslim Brotherhood, visited the Sinai peninsula in October to meet with and reassure Coptic families, telling them that “your security is our security”.
Egypt's Copts, who make up six to 10 percent of the country's population of 83 million, have regularly complained of discrimination and marginalisation and have also been the target of numerous sectarian attacks.
One of the worst incidents of violence occurred on January 1, 2011 when 23 people were killed in an attack on a Coptic church in the Mediterranean city of Alexandria.
Sinai, a scarcely populated peninsula home to lucrative tourist resorts in the south and shadowy Islamist militants in the north, is a major transit point for arms smuggling to Gaza which is ruled by the Islamist Hamas group.
Security in the desert and mountainous region collapsed after the uprising that toppled Mubarak.
Since his downfall, several militant attacks have targeted police and soldiers, including a brazen August 5 ambush on an army outpost that killed 16 soldiers.
The military launched a wide-ranging campaign after that attack to flush out militants, but drive-by shootings have continued.
And on Friday security officials announced the seizure in Sinai of U.S.-made anti-tank and surface-to-air missiles destined for Gaza, where militants have said they would acquire more weapons to use against Israel.
