It took less than five seconds for the building in southern Beirut<\/a> to be reduced to rubble.<\/p>\n Residents heard the whoosh and watched as a missile slammed into the bottom of the multistory building, which then sank to the ground, a huge plume of gray smoke rising and debris flying after the strike.<\/p>\n Videos circulating on social media and verified by NBC News, showed several men watching the strike on Lebanon’s capital<\/a> from a distance, standing by their cars as the building crumples. Others drove their motorbikes away from the scene.<\/p>\n In another video, one man can be seen running from the strike as a colossal bang rings out. Four other men hurry away as one warns the others to \u201cmove back so that the flying stones do not fall on you.\u201d<\/p>\n A third video that captures the strike from afar shows a cloud of dust washing through the neighborhood.<\/p>\n It was not immediately clear if there was anyone inside the building or if there were any casualties, but the strike was caught from multiple angles by people gathered outside.<\/p>\n \u201cThey targeted two buildings, not one,\u201d a man can be heard shouting in the third video. Two explosions can be heard in several of the videos, although it unclear where the second blast came from.<\/p>\n
