The president of Senegal offered his condolences via Twitter on Thursday after five people who immigrated to Colorado from the West African country were killed in a suburban Denver house fire that authorities say they suspect was intentionally set.

President Macky Sall tweeted in French that he was also monitoring the investigation closely, and he wished the surviving victims a speedy recovery. Three people escaped Wednesday morning's fire by jumping from the home’s second floor and are recovering from non-life-threatening injuries.

Police, fire officials and the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives are investigating the fire because there are indications that it may have been arson, said Joe Montoya, division chief of investigations for Denver police. Montoya would not elaborate Wednesday on the evidence because he said he did not want to compromise the investigation.

The Denver coroner's office has not released the names or ages of the victims, who immigrated from Senegal in recent years.

Senegal Consul General Elhadji Ndao flew to Denver on Thursday at the request of his country's leaders and said he is looking forward to the investigation.

Ndao, who was joined by members of the Senegalese community who gathered to mourn the victims, added, "It’s unfortunate that a whole family was gone in this tragic event.”

Denver Fire Department Capt. Greg Pixley said the victims' bodies were discovered after firefighters extinguished the fire, which was first reported by a police officer at 2:40 a.m. Wednesday.

“I awoke my husband, and he ran outside to see if he could help. But there was nothing he could do. The fire was too big,” Mendoza said.

A police officer trying to rescue people was pushed back by the fire’s heat. It appears that those who died were all on the first floor.
