There's been a fourth day of protests in Jordan over the government's decision to remove energy subsidies. The scrapping of the subsidies has increased the cost of petrol by more than 10 per cant, while cooking gas costs have been driven up by more than half. For the first time, the protesters, who are also angered by inflation and unemployment, have been calling for the end of the monarchy. Al Jazeera's Nicole Johnston reports from Amman.
