CAIRO, Sept. 7 (Xinhua) -- Several militants were killed and dozens injured on Saturday in a raid launched by the Egyptian army on hideouts of Jihadist militants in North Sinai governorate bordering Israel, a local security source told Xinhua.
The raids targeted 12 villages in Sheikh Zuwaid city, and the clashes are still going on between security forces and militants, the source added.
"It is the biggest military campaign in Sinai since the 1973 war," the source added.
Around 2,500 soldiers and officers from the army, police and central security forces took part in the operation, the source said.
Three vehicles belonging to the militants have been destroyed, but the exact death toll was not clear yet, according to the source.
Security conditions are deteriorated in the Peninsula after toppling the Islamic President Mohamed Morsi, after which the army intensified its operations to eradicate the focal points of the terrorism and hardline Jihadist movements.
