Egyptian military reinforcements arrived Thursday (August 9th) near the Sinai border city of al-Arish in the biggest military deployment in the peninsula since 1979, Ahram Online reported.
The newspaper said the decision comes after the military reported that it killed 20 militants on Wednesday in response to the deaths of 16 border guards on Sunday in Rafah.
The deployment is part of "Operation Eagle", an operation in which Egypt deployed 2,500 troops and 250 armoured personnel carriers in Sinai in August 2011 in an aim to secure vital establishments in the region.
Al-Arabiya reported that clashes resumed in al-Arish between armed men and police forces, citing a Nile News television correspondent.
Meanwhile, in Cairo, Egyptian President Mohamed Morsi appointed Mohammed Rafaat Abdel Wahad Shehata as interim head of Egypt's General Intelligence Service after sacking on Wednesday its former head Murad Muwafi, AFP reported.
