he United States appears poised to launch missile strikes against the regime of Syrian President Bashar al-Assad, which is accused of using chemical weapons to kill hundreds of people near Damascus earlier this month. But this is hardly the beginning of the war. Syria has been consumed by violence for two and a half years. Here, a brief look at how the situation has escalated since 2011.
February 22, 2011
Inspired by the uprisings in Tunisia and Egypt, 15 teenagers write anti-regime graffiti on the walls of Dara, a small town in southern Syria. They are arrested and thrown into prison.
May 18, 2011
The United States imposes sanctions on Syria after a month of violent crackdowns by the Assad regime against protesters. Activists say at least 700 people have been killed.
July 31, 2011
Tanks roll into the central city of Hama, launching an attack before the first day of Ramadan that activists say kills 80 people, bringing back memories of the 1982 massacre of 20,000 people in the same city by Assad's father.
August 18, 2011
"For the sake of the Syrian people, the time has come for President Assad to step aside," says President Barack Obama. The leaders of Britain, France, and Germany join the United States in calling for Assad to resign.
November 12, 2011
The Arab League, which includes Egypt, Saudi Arabia, and 20 other countries, votes to suspend Syria's membership and threatens to impose economic and political sanctions if it doesn't stop the ongoing attacks against protesters.
February 4, 2012
International officials condemn the "massacre" in the city of Homs after an estimated 300 people are killed by a barrage of artillery fire from Syrian government forces. Shortly thereafter, China and Russia veto a resolution by the U.N. Security Council backing an Arab League peace plan for Syria.
August 21, 2012
President Barack Obama says Assad using chemical weapons would be a "red line" that would "change [his] equation" on Syria. Opposition activists put the death toll in the conflict at 20,000.
March 19, 2013
Rebels and the Assad regime accuse each other of using chemical weapons to kill 25 people in the Khan al-Assal region north of Aleppo. The White House announces there will be "consequences" if the Syrian government is guilty of the attack. More than 6,000 people are killed in March alone, activists say, making it the bloodiest month since the conflict began.
April 25, 2013
The White House says, with "varying degrees of confidence," that it believes the Assad regime "used chemical weapons on a small scale" on March 19.
June 13, 2013
The Obama administration announces it will send small arms and ammunition to Syrian rebels. The decision is later debated by Congress over fears that the United States could be arming al Qaeda-linked opposition groups like the Al-Nusra Front.
July 25, 2013
The United Nations announces that 100,000 people have been killed and 1.7 million people have been forced to become refugees as a result of the violence.
