A policeman got into an argument with a vendor over the price of a cup of tea. The policeman shot the vendor dead and injured two others. The incident happened in a Cairo suburb.
The killing is the latest in a series of incidents in recent months. The Egyptian public is angry about police brutality. There was a riot after the latest incident.
Difficult words: vendor (a person who sells something), suburb (an outer city area where people live), riot (a violent, angry protest).
