An explosive device went off close to a police station in Alexandria, killing one and injuring two others on Tuesday morning, according to state-run MENA.

Allegedly, all three were Muslim Brotherhood members, and they were attempting to plant the bomb when it went off.

Another bomb went off Tuesday morning in Port Said near the temporary headquarters of the Workers’ Union Federation. No casualties were reported.

Several other explosive devices were found in Fayoum and Cairo on Monday, leaving no casualties.

One bomb was defused in Nasr City’s City Stars shopping mall, entailing its evacuation, according to state-run newspaper Al-Ahram.

In a separate incident, nine explosive devices were found in the vicinity of a church and a mosque in Fayoum, which were defused by police officers.

Cairo Governor Galal Saeed noted that an EGP 100,000 reward will be provided to those who defused the devices in recognition for their efforts.

A number of policemen have lost their lives over the past year whilst dismantling bombs. Some were videotaped as the devices went off, with the videos going viral on social media networks.

The most recent case took place on 6 January, when a policeman was killed in a blast while dismantling a bomb in Giza, Greater Cairo, in front of Al-Talbeya police station.

Since the ouster of president Mohamed Morsi in July 2013, Egypt has experienced several bombings, particularly targeting police stations and security personnel. Most of these attacks were claimed by militant groups operating in Egypt, including ‘State of Sinai’ and Ajnad Misr, who reject the current regime.
