Security has been stepped up across India after bombings brought more bloodshed to Mumbai.
The country’s financial hub has been hit by repeated attacks in recent years. Wednesday’s near-simultaneous blasts in three districts killed 18 people and injured dozens more.
As vigilance is increased police are examining security camera footage and forensic clues. Terrorists are being blamed by authorities, keen to stress who is and is not their target.
“The target is India’s unity, integrity, prosperity. There are elements that are hostile to India and do not wish India to grow and prosper,” Home Minister Palaniappan Chidambaram told a news conference.
“When an incident like this happens, let me assure you, it is not targeted against any foreigner. It is not targeted against any tourist visiting India.”
The involvement of a suicide bomber is not being ruled out. No group has claimed responsibility for India’s deadliest attacks since 2008. Then, Pakistan-based militants were blamed for killing 166 people in Mumbai.
