The mother of Egyptian policeman Amr Shebl, who was killed in an attack on two buses packed with Egyptian policemen near the border town of Rafah, in northern Sinai the previous day, is comforted by a relative as she mourns, holding pictures of her son at her home in Salmun Bahri village, in the Egyptian Delta region of Menufiya, 50 kms north of the capital Cairo on August 20, 2013. Militants killed 25 policemen in the deadliest attack of its kind in years, as Egypt's army-installed rulers escalated a campaign to crush ousted president Mohamed Morsi's Muslim Brotherhood.
