Twenty-four hours have passed since an explosion claimed several lives and injured dozens in East Harlem. Mayor Bill de Blasio again visited the site where efforts have been underway to rescue folks in the rubble of 1644 and 1646 Park Ave. in Manhattan. City officials say seven people are confirmed to have died in the blast and its aftermath and at least five people remain missing.
Every day, people break news on Twitter first. This creates a new real-time global sensor network of eyewitnesses at events as they unfold.
