CAIRO, Nov 5 (Aswat Masriya) - The death toll of the explosion which occurred inside a train station in the northern governorate of Menufia late Wednesday rose to four, including two policemen and two civilians.

An Improvised Explosive Device (IED) exploded in the last cart of a train in the Menuf train station, injuring eight, reported state-run news agency MENA. Civil protection forces were able to put down a fire which erupted after the explosion.

A security source, who preferred to remain anonymous, said that Homeland Security in the governorate of Menufia launched a security campaign to arrest Muslim Brotherhood leaders in the city. The source added that security forces raided the houses of a group of Brotherhood members and arrested a number of them.

The Muslim Brotherhood has come under attack since the military ouster of its leader Mohamed Mursi from the presidency in July 2013 following mass protests against his rule. The military-installed regime has since then rounded up thousands of Brotherhood members and supporters and killed hundreds of protesters in confrontations with security forces.

Egypt listed the Brotherhood as a terrorist organisation last December and insists it is behind the stringent wave of militancy which has targeted security personnel since Mursi's ouster. The Brotherhood continuously denies the accusations, distancing itself from one militant attack after the other.
