The demonstrations were organized mainly by the country's Islamist opposition.
The government of Prime Minister Faiz Al-Tarawneh announced its decision to raise petrol prices by 10% on Saturday - the second price hike this year. According to a government spokesman, the move was aimed at cutting subsidies in order to ease the state budget. The price of 1 liter of 95-octane gas was slated to reach 1 Jordanian dinar (about $1.4).
The protestors' anger was directed at the government, with one of the rallies being held outside the Interior Ministry, considered to be the strongest institution in the kingdom.
According to local reports, a majority of parliament members were planning a no-confidence vote against the government in response to its decision.
The Jordanian economy has been suffering in light of the global and regional financial crises. As it is mostly based on the import of energy sources, the global increase in oil prices has a destructive affect on the country's treasury.
During the first half of the year, Jordan imported 97% of its energy sources at a cost of $3.5 billion.
The situation in Syria is affecting the Jordanian economy as well. The ongoing influx of refugees has been creating additional pressure on the kingdom's treasury.
Several days ago, the Jordanian government issued an urgent request to the international community for $700 million in aid in order to help care for the Syrian refugees arriving in the country.
