Unrest in Middle East and North Africa

CNN Wire Staff

(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.
