The United States has offered its "deep condolences" for the 349 people so far confirmed dead during a stampede that occurred on the final day of Cambodia’s water festival.

"On behalf of President Obama and the people of the United States, I offer our deep condolences for the tragic loss of life and the injuries in Phnom Penh during Cambodia's annual water festival," said Secretary of State Hillary Clinton.

She praised the "strength and resilience" of Cambodian people, traits she observed during her visit to the Kingdom this month.

"Our thoughts and prayers are with the family and friends of the victims and with all the people of the Kingdom of Cambodia," she said.

"I am confident that they will pull together and persevere through this difficult time."
