Egypt arrests church bombings suspect
The ministry said the groups were Hasm and Lewaa al-Thawra. The Brotherhood, which says it is a peaceful organisation, was banned by the government after the overthrow of President Mohamed Mursi, who had been the Brotherhood candidate, in 2013.
Hasm claimed responsibility for an attack that killed three policemen in Cairo on Monday. Little is publicly known about Hasm, though it has claimed a handful of attacks over the past year.
