ISIS Claims Deadly Dual Beirut Bombings

Report: At least 37 killed in bombing in Lebanese capital.

In statements circulated on Twitter and through the Telegram messaging app, ISIS said it detonated a motorcycle bomb in the Lebanese capital and then, after witnesses rushed to the scene, a suicide bomber unleashed another deadly blast on the crowd.

An official with the Lebanese Red Cross told a state media organization that the blasts killed 37 people and wounded 180 others, according to The Associated Press. Citing a local security official, the AP reported a third bomber was found dead while wearing an intact suicide vest, possibly an unintended victim of the second bomber's blast.

The neighborhood where the bombs went off, Burj el-Barajneh, is one of the most densely populated areas in Beirut. It lies within the so-called Hezbollah security perimeter, but it is also home to a diverse Lebanese population as well as one of the biggest Palestinian refugee camps in the country.

A Lebanese law enforcement official told ABC news that two of the perpetrators were Palestinian and the third was Syrian, as was also reported in the local press.
