Sinai Attack: Funeral of martyrs

A relative of martyr bewails during a funeral for soldiers, who were killed during an attack at a checkpoint along the Sinai border with Israel by unknown gunmen, near the tomb of the late former President Anwar al-Sadat and the Unknown Soldier monument in Cairo August 7, 2012. Egypt began work to seal off smuggling tunnels into the Gaza Strip on Tuesday, a security source said, two days after gunmen shot dead 16 Egyptian border guards in an attack blamed partly on Palestinian jihadi militants.
