Egyptian security forces arrested on Monday several Muslim Brotherhood members countrywide, including a former scientific adviser to ousted President Mohamed Morsi.

Nasser Saber Khalil, a senior Brotherhood member and a scientific adviser to the deposed leader, was arrested at his home in Suez, a security source told the Anadolu Agency.

Khalil faces charges of incitement to violence.

Other Brotherhood members were reportedly arrested in the provinces of Sharqiya, Kafr al-Sheikh, Beni Sueif, and Luxor.

Egyptian authorities have unleashed a massive crackdown on Brotherhood leaders since last month's dispersal of two sit-ins by Morsi supporters, in which hundreds of protesters were killed.

Hundreds of the group's high and mid-ranking figures, topped by supreme leader Mohamed Badie and his deputies Khairat al-Shater and Rashad Bayoumi, are now in jail.
