A tragic incident in a wedding in India has taken people by surprise. A wedding gift given to a newly married couple exploded just days after the wedding, killing the groom and his grandmother.

The explosion has also left the bride in a critical condition and could possibly die.

The man’s grandmother also died in the blast. The incident took place in Odisha’s Bolangir district on Friday, just five days after their wedding, the police said.
