(CNN) —  

One soldier was killed and eight wounded in an attack on a military camp in the Sinai city of Rafah near the border with Gaza, the state-run news website Egynews reported Monday.

The website attributed the information to security and medical officials.

The continuing violence in the Sinai region is adding to the strain in Egypt, which is struggling with a weak economy and political unrest stemming from a coup that ousted President Mohamed Morsy.
