No other details were provided by the TV station, but other News services reported that 4 people were killed in the explosion.
Live television footage showed the aftermath of Sunday’s blast, which brought a tree down on a nearby car. Policemen with sniffer dogs were scouring the area for more bombs, according to a report by Al Jazeera.
Armed groups have killed scores of policemen in bombings and shootings since Egypt’s military toppled Islamist president Mohamed Morsi in July 2013.
Fighters have in the past set off several bombs in succession, to target first responders after the initial attack.
