ISIS Egyptian affiliate claimed responsibility for attacks that took place earlier Saturday against security personnel in Egypt's Giza.

"Some elements belonging to our organisation targeted a security checkpoint in Giza's Abu El-Nomors town using light weapons, leaving all security personnel dead," militant group Ansar Beit Al-Maqdis said in a statement released hours after the attack.

However, a security source said told the MENA state news agency that unknown assailants shot dead a police colonel along with a conscript in their police vehicle while exiting the colonel’s farm, heading to their work premises.

Egypt has been battling an Islamist insurgency, mainly based in the North Sinai region, that has killed hundreds of police and troops since the 2013 ouster of Islamist president Mohamed Morsi.

Militant group Ansar Beit Al-Maqdis, which swore allegiance to the IS group in November 2014, has claimed responsibility for most of the deadliest attacks on security forces in Egypt.
