(CNN) -- Unrest has spread across the Middle East and North Africa. Here's a look at what has happened -- and what is happening -- in various countries:





ALGERIA





Authorities in Algeria said Monday that they would lift a 20-year state of emergency in the "coming days." They acted after anti-government protesters chanting "change the power!" clashed with security forces in the capital over the weekend, witnesses said. The state of emergency was imposed in 1992 to quell a civil war that led to the deaths of what U.S. officials estimate to be more than 150,000 people. About 100 protesters were arrested during the protests in Algiers on Saturday, according to the opposition Algerian League for Human Rights.





BAHRAIN





Protests were scheduled to take place Monday afternoon in the Persian Gulf nation of Bahrain, where at least three police officers and one demonstrator were injured in clashes Sunday, the state new agency reported. The injuries occurred during an attack on a police station during protests Sunday evening, the news agency said. After three officers were injured, police fired on protesters with rubber bullets, causing one injury, the news agency said.





EGYPT





Unrest persisted in Egypt on Monday even after an 18-day revolution toppled longtime President Hosni Mubarak, who stepped down Friday. Egypt's banks remained closed Monday after protests by National Bank workers apparently drove out the head of the institution. The nation's stock market remained closed until further notice because of turmoil in the banking sector. In addition, current and former police officers continued a peaceful protest Monday in front of the Interior Ministry, saying they want higher pay, shorter hours, better benefits and more respect. And some police officers told reporters they were ordered to shoot protesters during demonstrations last week and threatened with prison if they did not.





IRAN





Tens of thousands of demonstrators marched along Revolution Avenue in downtown Tehran on Monday, protesting the government of Iranian President Mahmoud Ahmadinejad, witnesses said. The wave of people remained largely silent as they walked toward the capital city's Azadi Square, though some clashes between security forces and demonstrators broke out in several parts of Tehran, according to witnesses. Security forces fired tear gas in some places and detained demonstrators in other areas of the city. The Iranian government rounded up activists last week after opposition leaders Mehdi Karrubi and Mir Hossein Moussavi called for supporters to gather at Azadi Square -- the site of mass protests by Iran's opposition movement after the disputed 2009 presidential elections.





IRAQ





Thousands of people rallied this month in cities across the country, protesting rampant poverty, a 45% national unemployment rate and shortages of food, electricity and water. Most recently, hundreds of angry demonstrators took to the streets of Ramadi -- about 60 miles (100 kilometers) west of Baghdad -- to protest the government's inability to provide basic services. After the protests began, Prime Minister Nuri al-Maliki announced he would cut his salary in half amid the growing unrest over poor public services and water shortages. State television also reported this month that al-Maliki would not run for a third term when his current one expires in 2014.





JORDAN





U.S. Adm. Mike Mullen, chairman of the Joint Chiefs of Staff, traveled over the weekend to Jordan, where King Abdullah II swore in a new government last week following anti-government protests in his country. The new government has a mandate for political reform and is headed by a former general, with several opposition and media figures among its ranks. The appointment of new Prime Minister Marouf al Bakhit was seen as an attempt to shore up support among Jordan's Bedouin tribes -- the bedrock of the monarchy. Jordan's economy has been hard-hit by the global economic downturn and rising commodity prices, and youth unemployment is high, as it is in Egypt. Officials close to the palace have told CNN that Abdullah is trying to turn a regional upheaval into an opportunity for reform.





LIBYA





There were calls made through Facebook for a day of peaceful demonstrations in Libya on Monday. The protests come in the shadow of leader Moammar Gadhafi, who has ruled the country for almost 40 years and had expressed support for former Egyptian
