At least 10 people were killed as Egypt’s army launched an air and ground assault on Sinai militants Saturday while foiling a railway bombing near the canal city of Suez, officials said.
A prosecutor levelled new accusations meanwhile against Mohamed Morsi, already facing trial on other charges, alleging the Islamist leader insulted the judiciary when he was president, state media said.
Egypt has seen an uptick in bombings and shootings, mostly aimed at the security forces, since August 14 when hundreds were killed in clashes when police broke up two pro-Morsi protest camps in Cairo.
The military has been facing an insurgency in north Sinai, a haven for Al-Qaeda-inspired militants who launch almost daily attacks against security forces.
And on Saturday it pressed a crackdown on suspected Islamist militants on the restive peninsula.
Reuters puts the number of militants killed at 31.
