CAIRO — A visibly angry Egyptian President Abdel Fattah El-Sisi pledged tougher laws against militants at the funeral on Tuesday of top prosecutor Hisham Barakat, assassinated in a Cairo car bombing. “The arm of justice is chained by the law. We're not going to wait for this. We're going to amend the law to allow us to implement justice as soon as possible,” Sisi said in a televised speech surrounded by Barakat's mourning relatives.Violence continued even as Egypt prepared for Barakat's funeral. In the northern Sinai city of Sheikh Zuweyid, a mortar shell allegedly fired by extremists at an army position fell on a private residence, killing two children and wounding three others, family members said. And in the city of Beni Suef along the Nile River south of Cairo, security officials said gunmen opened fire on a police car, killing a sergeant and wounding four others. — Agencies
