The attack in Oak Creek, Wisconsin, left seven people dead, including the shooter.
Hindi cine stars, upset with the attack on religious sects, took to Twitter to share their thoughts. Here's what they had to say:
Amitabh Bachchan: What is happening in US? Another shooting of innocents! And inside a temple, a gurdwara! Pained and shocked beyond words. Prayers for those affected.
Anupam Kher: Attack and killing of innocent people in a gurdwara in America is a sad and cowardly act. My heartfelt condolence to the families of victims.
Shabana Azmi: We condemn the loss of innocent lives at Sikh gurdwara, Wisconsin and pray for the swift recovery of injured. When will this madness end? Attacks at houses of worship (Wisconsin) must be condemned by all. This type of crime strikes at the very foundation of religious freedom.
Sophie Choudry: Absolutely shocked about the Wisconsin gurdwara shooting! Prayers and condolences. Cinemas, college campuses and now temples... Is no place safe?
Onir: Anguished at the gurdwara shootout in US. When will race/religion/gender hate crime stop. Once again we see the worst aspect of human beings.
Pooja Bedi: Shocked and saddened by the shootout at Milwaukee gurdwara! Strength to victims' families. I hope his sentencing is severe and swifter than Kasab's!
Vishal Dadlani: What on earth is wrong with this world? Why are people just killing innocent people for no reason?
