OTTAWA - Two Canadians were injured in the bloody terrorist attacks in the heart of India's financial capital, Mumbai, Foreign Affairs Minister Lawrence Cannon said Thursday.

Meanwhile, Canadian diplomats in the city were scrambling to track down and confirm the safety of other Canadians.

Cannon did not identify the two wounded, but Indian foreign ministry officials, speaking on background, identified them as Michael Rudder, of Montreal, and Helen Connolly, of Toronto.

They are among at least 16 wounded foreigners.

Canadian government officials, speaking on background, also said six Canadians were being held hostage by the Mumbai gunmen.

The officials said Prime Minister Stephen Harper was told about the six early Thursday and the government set up an internal crisis team to deal with the situation.

Cannon did not confirm whether the injured were among the Canadian hostages.

Consular staff are checking on their whereabouts of all registered Canadians in Mumbai, Cannon said in a telephone statement.

The problem, he noted, is that many Canadians visiting that country for tourism or business do not register with government agencies.

"I want reassure Canadians that our government -- in collaboration with officials in Mumbai and Indian authorities -- are doing everything in our power to protect and secure Canadians in Mumbai," Cannon said.

"Given that many Canadians are not registered, consular staff are requesting emergency co-ordinators follow up with any Canadians they know to be in Mumbai."

The Foreign Affairs Department has slapped a travel advisory on Mumbai, recommending that Canadians avoid all non-essential travel to the embattled city.

Harper telephoned India's high commissioner-designate in Ottawa to express his shock and sympathy to the Indian government, but made no mention of potential Canadian casualties.

"He expressed his condolences and horror at what had happened," said Shashishekar Gavai, recently appointed India's representative in Ottawa.

Gavai told CTV NewsNet that Harper "did not mention anything in particular about Canadian hostages, but I assume we will have wait to see what the actual situation is."

The prime minister told him Canada stands ready to "offer any support it can to the government of India to restore order and bring the perpetrators to justice," said a statement issued by Harper's office.

Information coming out of Mumbai, formerly known as Bombay, is sketchy and Indian officials in Canada were relying on news broadcasts, Gavai noted.

Authorities say the terror attacks at 10 Mumbai locations killed at least 119 people and injured about 300 others.
