Egypt arrested six Muslim Brotherhood members in connection with allegedly killing of Public Prosecutor Hisham Barakat last year and ordered their detention for 15 days, a judicial source and the state news agency reported on Sunday.
Barakat, 64, was killed by a car bomb in Cairo in June 2015. He was the most senior state official assassinated since the toppling in mid-2013 of elected President Mohamed Morsi. There was no claim of responsibility for the attack at the time.
Egyptian Interior Ministry Magdi Abdel Ghaffar accused Muslim Brotherhood officials of allegedly conspiring with Hamas to assassinate Barakat. He said that Hamas helped to provide training and explosives.
Ghaffar reported that the authorities had arrested 48 members of Muslim Brotherhood.
Morsi, Egypt’s first democratically-elected president, who was toppled in a July 2013 military ouster led by current President Abdel Fattah el-Sisi, then head of the armed forces, was sentenced to 20-years in prison on April 21.
Sisi's government was quick to launch a violent crackdown on peaceful protests, labeling the Muslim Brotherhood a terrorist organisation and its supporters as terrorists. He banned the Brotherhood and jailed thousands of its supporters. Security forces killed hundreds of Mursi supporters in a single day in the bloodiest episode in Egypt's modern history.
The crackdown, which has included restrictions on freedom of protest, has angered many opponents of Sisi who has struggled to suppress an insurgency that is raging in the Sinai Peninsula which borders Hamas-controlled Gaza.
The Sisi administration blamed Muslim brotherhood for the prosecutor's death, even though the Brotherhood immediately condemned the attack and denied any possible affiliation to the assassination.
