Three terrorist elements were killed on Thursday night when a car and a bomb exploded in two separate incidents in Sinai, security sources reported.

Two armed terrorist elements were killed when an explosive device they were attempting to plant on the side of Sheikh Zoueid-Goura road detonated, the sources said.

In a separate incident, a terrorist element was killed after his explosives-filled car was blasted during a police chase, they added.

In cooperation with the police, the armed forces have launched a security crackdown on Sinai after militant extremists intensified their activities in the area following the removal of former President Mohamed Mursi from power last July.

Army and police forces have been a target for militants almost every day since July. Around 100 military and police personnel have been killed since then.
