ISMAILIA, Egypt, June 22 (Reuters) - The Egyptian army is digging a trench in northern Sinai along the border with Gaza in an effort to prevent smuggling, security sources said on Monday, as the government steps up activities to prevent militant attacks that often target security forces.
Egypt had already doubled to one kilometre (0.62 mile) the depth of a security buffer zone on its border with the Gaza Strip after some of the worst anti-state violence since President Mohamed Mursi was overthrown by the army following mass protests against his rule in 2013.
Authorities are still battling an insurgency in which the most active group, Sinai Province, has pledged allegiance to Islamic State. Hundreds of police and soldiers have been killed in the attacks, which have surged since the army ousted Mursi.
The trench would help detect more tunnels used in the smuggling trade, which Egyptian authorities see as a threat. Once the trench is dug, no vehicle or person will be able to pass except through the trench.
Security sources said passages had been made for vehicles and for pedestrians. They said the U-shaped trench is two kilometres away from the border and will have a depth of 20 metres and a width of 10 metres.
Some residents criticised the trench, saying it had choked traffic and had caused the destruction of vegetation, which many farmers in the area depend on.
