On Sunday afternoon, the centre of Khartoum witnessed hundreds of people waiting in vain for public transport.
Many people were forced to return home on foot, a resident of Omdurman told Radio Dabanga.
According to officials, only 9,000 out of the about 20,000 city buses in Khartoum are currently working.
Many bus owners cannot afford to operate the buses because of the high operating costs, caused by recurrent maintenance expenses and soaring fuel prices.
An official of the Khartoum Transportation Association earlier acknowledged that the buses imported from China over the past two years are not meeting the quality standards.
On 3 November, the Sudanese government lifted the subsidy on fuel tariffs, the first of a series of austerity measures taken “to avoid the collapse of the country” as President Omar Al Bashir stated. The petrol and diesel prices began to soar immediately.
