What appears to have been a car bomb detonated in the Lebanese capital of Beirut Friday morning, shaking a country that has feared the spread of violence from neighboring, war-torn Syria. "Those who've lived through Lebanon's wars say today's explosion inevitable result of conflict in Syria," NPR's Kelly McEvers wrote on Twitter. "Many surprised it took this long."

We still don't know who planted the bomb in downtown Sassine Square, where it has killed at least eight so far, or why. Elias Muhanna, a blogger on Lebanese news, pointed to an August Al-Monitor story for political context. The article explored the implications of Lebanon's arrest of Michel Samaha, a former Lebanese politician believed to have ties to the Syrian regime, on charges of planning to bring explosive into Lebanon from Syria.

For the moment, all we can know with any certainty is what's happening on the ground in Beirut. That story is hinted at in these dramatic, and at some points harrowing, photos from Friday.
