An explosion took place Sunday in North Sinai's Sheikh Zuweid city and left an Egyptian army officer injured, Al-Bawaba News reported. Two improvised explosive devices have targeted a military armored vehicle during a security campaign held in the city searching for some terror suspects. The injured officer was transferred to Al Arish military hospital for treatment. Since September 2013, the Egyptian army has been carrying out an ongoing military campaign against terrorist groups in Sinai after they claimed responsibility for several deadly attacks targeting Egyptian military and police personnel.
