Brussels - European Union foreign policy chief denounced on Thursday the “heinous” triple bombing in Mumbai that killed 17 people and said the perpetrators must be brought to justice.

Ashton “was horrified to hear that Mumbai has again been the target of a series of deadly bomb attacks,” her office said in a statement.

“She condemns these heinous acts and expresses her condolences to the families and friends of the victims. It is essential that the perpetrators these evil attacks are brought to justice,” the statement said.

The three bomb blasts that ripped through crowded areas of India's commercial capital on Wednesday evening were the deadliest attack on Indian soil since the 2008 assault on Mumbai by militant gunmen that left 166 dead. - Sapa-AFP
