Overseas Indians have joined world leaders in strongly condemning the serial blasts in Srinagar and Mumbai and said that targeting innocent people was an "unjustified and unforgivable criminal action".
"We strongly and categorically condemn these most reprehensible acts of crime against innocent people," Inder Singh, president of the Global Organisation of People of Indian Origin (GOPIO), said in a statement.
"We share the pain and anguish of our brethren and sisters in India, and extend our condolences to the families of the victims and offer prayers for the speedy recovery of those injured," said the statement.
Around 180 people were killed and hundreds injured in seven consecutive train bombings in India's financial capital Mumbai on Tuesday evening hours after eight people died in five explosions that rocked Jammu and Kashmir's summer capital Srinagar city.
The organisation said the blasts were directed to create fear among the Indian people.
Commending the Indian government and the state administrations for their "diligent efforts in providing emergency services to the victims' relatives and prompt treatment to the injured", GOPIO said it would also support the government for its efforts to bring peace and confidence among people.
"We are very confident that the people of India will survive this national disaster and will retain courage, sense of dignity, their values and their freedom. There is no doubt that a resilient nation as India will overcome this brutal and senseless attack," said KN Gupta, president of the GOPIO chapter in national capital.
According to the statement, GOPIO has set up a relief fund for the victims of the bomb blast.
"Your charitable contribution can be mailed to GOPIO Inc, PO Box 1413, Stamford, CT 06904, USA," it said.
GOPIO can also be contacted at email@example.com or by telephone (818) 708-3885 or (203) 329-8010.
Another North America-based organisation, the American Federation of Muslims of Indian Origin (USA & Canada) also expressed its "shock and outrage at the barbaric and inhuman bomb blasts in Mumbai".
"This was a cowardly act of violence clearly aimed at innocent civilians," said Akram Syed, president of the organisation, urging the government to bring the perpetrators to justice swiftly.
Volunteers of the Maryland-based Association for India's Development (AID) also expressed their solidarity with the survivors of Mumbai blasts.
"In these trying times, our prayers and thoughts go to all the survivors of this horrendous act of violence and their families and friends," it said in a statement.
The volunteers appealed to the government to ensure that the survivors receive medical and financial help expeditiously and the perpetrators are brought to justice quickly.
