Mr Hassan, 38, who worked for the local Shaab Misr newspaper, was killed on 28 June in an explosion that is believed to have been caused by a home-made hand grenade while reporting on a protest against Egyptian President, Mohamed Morsi, in the city’s Al-Shuhada Square.

"We mourn the death of our colleague who was senselessly murdered while carrying out his professional duty," said IFJ President Jim Boumelha. “Mr Hassan, who leaves a wife and two children, was a dedicated journalist who was there to observe and report on the protest. Those responsible for his brutal murder must be brought to justice and pay for their crimes."

Another 15 people were injured by the explosion. Initial reports had suggested it was caused by a butane cooking gas cylinder, but security sources have ruled this out.

The Egyptian Journalists Syndicate (EJS) has condemned the “brutal attack” and expressed its great sadness at the loss of a highly respected colleague and friend.  

In light of growing tensions in Egypt, the IFJ has advised journalists in the country to exercise extreme caution. 

“We are becoming increasingly concerned about the growing incidents of violence in Egypt," said IFJ General Secretary Beth Costa. "We urge journalists covering the social and political unrest there to be extra vigilant and ensure they protect themselves."
