Fear in Cairo after police officers shot dead
No one has claimed responsibility for the killing of the police officers.
CAIRO - Egyptians have been cautioned about their safety following the drive-by shooting of four policeman.
The fatal incident happened not far from the capital, Cairo.
It comes just days after the Islamic State's Egyptian branch claimed responsibility for a bombing that killed at least seven people (including a judge), and injured scores of others in a hotel in North Sinai.
No one has claimed responsibility for the killing of the police officers, yet.
There are security checkpoints on most roads in Egypt.
Some of them are random - you could be asked for your passport, your car could be thoroughly checked or you could just pass by.
Masked gunmen on motorcycles opened fire on the security checkpoint close to a famous step pyramid.
It was not busy with tourists visiting at the time.
Now those in the area, and in the capital Cairo have been asked to remain vigilant of their surroundings and while moving around the area.
Security forces and other elements of the state have been under attack predominately in the Sinai area where a hotel was attacked on Tuesday.
Soldiers and police have been the most marked.
