A man thought to be Iranian has had both legs blown off after attempting to throw a bomb at police in the Thai capital, Bangkok, officials said.

Two other explosions were reported in the same busy commercial district of the city, injuring four other people.

Police said one blast took place at the house the injured man rented with other Iranians. One of those men also threw a bomb at a taxi in the capital.

Last month the US embassy warned of possible attacks in Bangkok.

The blasts come just a day after two bomb attacks targeted Israeli diplomats in India and Georgia.
