An employee at North Sinai's traffic administration was gunned down early Saturday by unidentified assailants, police sources said.
The sources, who preferred to remain anonymous, told Aswat Masriya that the employee, a Copt, was shot in the head in front of his family. The three assailants attacked him under the pretext of his cooperation with security apparatuses.
The deceased employee lived in the city of al-Arish. His body was transferred to the Arish General Hospital, the sources said.
The number of security personnel and civilians killed in armed attacks by militants in North Sinai significantly surged during the past few months.
At least 30 people were killed and 50 others were injured late Thursday in four separate attacks against security installations in the governorate.
Thursday's attack is the deadliest since a similar attack on the Peninsula last October. At least 30 military personnel were killed in a suicide operation which targeted a security checkpoint in Sinai's Sheikh Zuweid on October 24, 2014.
In a video allegedly released by the Ansar Bayt al-Maqdis militant group in August 2014, the group claimed responsibility for beheading four Egyptians, accusing them of providing intelligence to Israel.
The group has also warned inhabitants of Sinai against "cooperating with the Jews and spying on their fellow Muslims", urging those involved to repent to be pardoned.
Similar executions of civilians have been repeatedly occurring since then, gripping the lives of dozens of residents.
