Egyptian security forces made 10 more arrests yesterday in their investigation into a spate of deadly bombings that have rocked the Sinai peninsula over the past year, a security official told AFP. âSecurity forces have launched a vast arrest campaign in Jabal Halal in the central Sinai peninsula in the course of which 10 men were detained,â he said. âThe 10 are currently being questioned to establish whether they participated in the attacks on Taba, Sharm El-Sheikh and Al-Gurah.â A firefight erupted before the men were arrested but there were no immediate reports of casualties, the official added.He said 25 improvised bombs had been recovered from caches in the areaâs sandy mountains. Around 150 people have been arrested over the past week in raids across the Sinai peninsula. Two elite police officers were killed in twin blasts in Jabal Halal Thursday as they searched for suspects in the deadly Sinai bombings. Two Canadian peacekeepers were lightly wounded when a homemade bomb struck their vehicle on Aug. 15 in an area of the peninsula not far from the border with the Gaza Strip.
