At least eight people have been injured in clashes that broke out in Jordan's capital between government supporters and opponents at a protest calling for more freedom and lower food prices.

The protest was the seventh straight Friday that Jordanians took to the streets demanding constitutional reform and more say in decision-making.

Jordan's king enjoys absolute powers, ruling by decree: He can appoint and dismiss cabinet and parliament whenever at anytime.

Amani Ghoul, a teacher and member of the movement that organised the protests insisted the protests will continue until their demands are met.

"We want a complete overhaul of the political system, including the constitution, the parliament dissolved and new free and fair elections held," she said.
