3 police officers were killed and 4 people, including a police officer, were wounded in an armed attack targeting a security checkpoint in the city of Ismailia, northeast of the Egyptian capital, Cairo, on Friday evening, according to security and medical sources.

And the French Press Agency quoted security sources as saying that two cars approached the security barrier established in the residential neighborhood of Al-Salam, and two people got out of them, each carrying an automatic weapon, and opened fire at the security personnel.

The sources indicated that the police responded to the attackers, killing one of them and wounding another, but he managed to escape.

For its part, Reuters news agency quoted sources at the Egyptian Ministry of Interior and the Security Directorate of Ismailia that two gunmen on two motorcycles opened fire at a security checkpoint, killing two policemen and a citizen, and two other policemen were wounded in the attack.

The sources added to Reuters that one of the gunmen was killed while the second escaped with the help of others.

In the context, Al-Ahram and Akhbar Al-Youm (two government) newspapers said that the security services managed to thwart a "terrorist attack" on one of the security checkpoints (ambush) in Ismailia Governorate, and the perpetrator of the attack was killed by the ambush personnel.

The two newspapers published a picture they said was of the attacker, without further details.

And Egyptian media reported that the security forces imposed a security cordon after an attempt to attack a security force in the vicinity of the Al-Salihin Mosque in Ismailia Governorate, noting the extensive deployment of vehicles to detect and defuse explosives and civil protection in the area.

Security sources told AFP that the attack was a "terrorist act", the first of its kind in an Egyptian city in years, with the exception of North Sinai, where the Egyptian branch of the Islamic State is active.

Last May, 11 soldiers were killed in an attack in West Sinai.
