Three die in China sale stampede

Three people have been killed and more than 30 injured in a stampede at a supermarket sale in China.

The stampede happened at a branch of the French chain Carrefour, in the city of Chongqing, state media said.

The shop was offering large discounts on cooking oil. A crowd that had been waiting hours for the store to open then burst through the doors.

Carrefour entered the Chinese market in 1995 and has since opened more than 100 supermarkets.
