Citizens of Lebanon held a national day of mourning Friday after 43 people were killed and more than 200 wounded in twin suicide bombings that occurred Thursday.

The attacks occurred in the capital city of Beirut, one inside of a bakery and the other just outside of a Shia mosque, and was the deadliest bombing in the city since the end Lebanon's civil war in 1990. ISIS has said they are responsible for the attacks.

The Washington Post reported that the first bomber struck with an explosive-triggered motorcycle while the second wore a suicide vest. Officials said the two bombers struck close together in a congested area during rush hour to maximize harm. A third bomber was also in place but was killed by the explosives of the second assilant before he was able to detonate his explosives.

Prime Minister Tammam Salam said in a statement "I pray that this tragedy is enough to wake up politicians so that they can put their differences aside so we can protect the country."

Among the victims were three Americans from Dearborn, Michigan including a mother of two who went to Lebanon in attempts to bring her family to the U.S and a married couple who's 3-year-old son was injured during the attacks the Detroit News reported.

While Lebanon was in mourning, the city of Paris went dark at the hands of another terrorist attack that claimed the lives of over 120 people and wounded 200 others. Dozens of buildings and momuments around the world including the World Trade Center lit up in French colors to express support and unity and Saturday Facebook users across the country and world showed their support through themed profile picutres with the French flag.
