CAIRO — Egypt announced steep increases in fuel and cooking gas prices on Saturday as part of austerity measures intended to overhaul the country’s ailing economy.

This is the third time the government has increased fuel prices since the measures were announced in late 2015. The authorities also raised transportation fares by up to 20 percent on Saturday, according to state-run news agency MENA.

Officials announced the increases as Egyptians were celebrating Eid al-Fitr, the holiday that comes at the end of the holy fasting month of Ramadan. In May, there were small demonstrations against an increase in fares for the Cairo metro.

Egyptians took to social media on Saturday to protest the new price increases. In recent weeks, the authorities have raised metro fares by up to 250 percent, drinking water by up to 45 percent, and electricity by 26 percent.
