Watch | 29 killed in Mexico fireworks market explosion

An explosion ripped through Mexico's best-known fireworks market on the northern outskirts of the capital on Tuesday, killing at least 29 people, injuring scores more. The explosion sent a huge plume of charcoal-gray smoke billowing into the sky.It levelled the open-air San Pablito Market in Tultepec in the middle of the afternoon as it bustled with shoppers stocking up on fireworks to celebrate Christmas and New Year, reducing the vendors' stands to piles of rubble, ash, and charred metal.
