The Egyptian government removed fuel subsidies and put tax up on cigarettes, wine and beer last weekend.
The biggest price hikes are on the most commonly used fuels.
Acting prime minister Ibrahim Mahlab told Egyptians in a TV interview, “This is for your own good”.
But taxi and microbus drivers protested across the country. Many passengers refused to pay the higher bus fares.
Taxi driver Ahmed Abdullah said, “If president el-Sisi goes on like this he will not last for long and will face a similar destiny to Mursi.”
Muslim Brotherhood former president Mohamed Mursi tried to impose similar subsidy cuts in 2012 but was forced to withdraw them within hours because of the outcry.
The International Monetary Fund has been demanding subsidy cuts in return for loans to prop up Egypt’s failing economy.
