Three Canadians have been reported injured in Saturday's Bali explosions.

Dan McTeague, the parliamentary secretary to the minister of foreign affairs, says three Canadians were in one of the cafes, and suffered minor injuries. They have been treated at a clinic and released.

At least 25 people were killed and 100 are injured during two simultaneous attacks Saturday.

The blasts hit two packed seafood restaurants in Jimbaran beach and a bustling tourist shopping centre 30 kilometres away in downtown Kuta.

The attacks come almost three years to the day when bombings in Kuta killed 202, including two Canadians.

Those bombings, and two other subsequent bombings in Jakarta that killed at least 23, have been blamed on a group called Jemaah Islamiyah, which has been linked to al-Qaeda.

Indonesian President Suslio Bambang Yudhoyono has warned that more attacks could happen. "We will hunt down the perpetrators and bring them to justice," he promised. He warned people to be on alert.

Two Americans have been reported dead, and the United States has condemned the bombings on and offered to help.

"The United States stands with the people and government of Indonesia as they work to bring to justice those responsible for these acts of terrorism," Secretary of State Condoleezza Rice said in a statement. "We will continue to work together in our common fight against terror."

"Our deepest sympathy goes to the victims and their families and the people of Bali who have suffered meaningless violence before," said White House spokeswoman Erin Healy. "We also express our solidarity with the government of Indonesia and convey our readiness to assist in any way."

Western and Indonesian intelligence agencies have consistently warned that the extremist group would carry out more attacks.
