Egyptian authorities have arrested 25 al-Qaida-linked terrorists on suspicion of plotting attacks on oil pipelines and ships crossing the Suez Canal. The Egyptian Interior Ministry said the new cell was led by a Palestinian and included 24 Egyptians, mostly engineers and technicians. They planned to use mobile phones to detonate explosives against ships crossing the Canal, the statement said. The group learned how to make car bombs through communicating with al-Qaida terrorists on jihadi Web sites, according to an Interior Ministry statement. The detainees confessed to funding their activities through contributions from Islamic charities abroad and in one case robbed a jewelry store and murdered its Coptic Christian owner.
