Bangkok: Two "homemade" bombs exploded near a popular shopping mall in downtown Bangkok today evening, leaving one man with minor injuries, police said.

The blasts took place at around 8 pm (1300 GMT) near the busy shopping centre well visited by tourists and local residents, with police initially reporting they were caused by an electrical fault. Later today national police spokesman Prawut Thavornsiri told AFP further investigations had revealed the explosions were triggered by two IEDs (improvised explosive devices).
