Canadians killed in Mexico

At least five Canadian tourists and two hotel staff have been killed in an explosion at a luxury hotel on Mexico's Caribbean coast.



Officials say the blast, which is believed to have been caused by a build-up of natural gas, blew out windows at the 676-room Grand Riviera Princess hotel in Playa del Carmen.



At least 15 people were injured.



One child is reported to be among the dead.



Two Canadians are reported to be in a critical condition.



Others, including two US citizens and Mexican workers at the hotel, are said to be less seriously injured.



State officials say expert examiners and civil defence personnel will have to determine if the underground space filled with swampy water that remained when the building was constructed four years ago, could have generated the explosive gas.
