Six people died and three were injured following an oxygen cylinder blast which led to a partial house collapse in the Sikandrabad area of Bulandshahr district, officials said on Tuesday.

District Magistrate of Bulandshahr Chandra Prakash Singh said the incident occurred on Monday evening in the house of one Riyazuddin in which around 19 people, including women and children, were living.

Riyazuddin was involved in shuttering work — the process of giving support and stability to concrete during construction work before it becomes solid.
