Egyptian military helicopters have fired missiles on suspected Islamist militants in Egypt's northern Sinai peninsula, security officials have said.
Twenty people were reported killed in Touma village, while the Sheikh Zuwaid area to the west was also hit.
The strikes came after security checkpoints were allegedly attacked by gunmen in the town of al-Arish, leaving a number of people injured.
