A source in the Egyptian Interior Ministry was cited by the official MENA news service as saying a resident was plotting an attack on shipping lanes in the Suez Canal. The plan targeted foreign tankers passing near Ismailia province.
The area was the site of a discovery last year of a weapons cache that included eight surface-to-air missiles and three launch pads.
The Israeli military in August launched a raid on Egyptian targets after militants crossed the border in the Sinai Peninsula, killing eight Israelis. Six Egyptian security personnel were killed in the raid, stoking anti-Israeli sentiments.
The August attack was allegedly carried out in coordination with a group calling itself al-Qaida in the Egyptian Sinai, though it was unclear if the group has working ties with al-Qaida central or Hamas.
Natural gas pipelines in the region have been the frequent target of insurgent attacks.
