Smoke rises as a house is blown up during a military operation by Egyptian security forces in the Egyptian city of Rafah, near the border with southern Gaza Strip November 3, 2014. Egypt began clearing residents from its border with the Gaza Strip last week to create a buffer zone following some of the worst anti-state violence since President Mohamed Mursi was overthrown last year.
