Disturbing new video of the London high-rise blaze has emerged in which the screams of children trapped in the inferno can be heard pleading for help. A woman trapped on the top floor of the burning building posted a video showing intense smoke as she begs for assistance. The mother of two also opened her door to fellow residents, who join her in the apartment. She is among the many residents still unaccounted for. Meanwhile, singer Adele attended a vigil for victims of the fire Wednesday night.
