Egypt’s army spokesman said on Wednesday that sixty people have been killed while tens were injured and 103 arrested in a joint security operation launched by police and army forces on July 5 in the Sinai Peninsula. 

In a post on the army's official Facebook page on Wednesday, the spokesman added that the operation covered several locations, including Rafah and Sheikh Zuwaied. 

The arrested suspects are currently being interrogated. 

Army forces have also tore down 102 tunnels and 40 wells which were being used to smuggle fuel to Gaza. 

They also demolished four residences that were being used by terrorists as hiding places. 

Attacks against security forces and offices have increased in Sinai since the ouster of Islamist President Mohamed Mursi.
