Prince William has branded the killing of 10 people in Canada as "truly heartbreaking".
In a tweet, the Duke of Cambridge wrote: "The attacks at James Smith Cree Nation and Weldon, Saskatchewan are truly heart-breaking.
"Our thoughts and prayers are with the victims of these horrific acts and all those that have lost loved ones."
Adding a 'W' at the end of the message, the man second in line to the throne noted a personal statement, rather than an official one from the palace.
Canada was rocked by the stabbing spree in which 10 people were killed and 18 left injured in the province of Saskatchewan on Sunday, August 4.
The prince added: "Catherine and I send our best wishes to the people of Canada."
The awful attack caused a total of 13 different crime scenes
One of the two brothers wanted for the attack was found dead by Canadian authorities.
An officer said Damien Sanderson, 31, did not have injuries that were consistent with self-inflicted wounds when he was found at the James Smith Cree Nation indigenous community.
His body, according to police, was found in a heavily grassed area in proximity to a house that was being examined."
Damien and his brother Myles were both charged with the alleged killings at the community site, though the latter remains at large still and police believe him to be in the city of Regina.
Regina Police Chief Evan Bray said: "Is it possible that they're no longer in this community? It is possible but we don't have any information to disprove or point us either way.
"There's a lot of anxiety in our province right now in our communities and throughout the country and so we need to start the healing process and until we can make this arrest that isn't going to happen."
Police have not said if they believe him to be responsible for his brother's death and said he could be injured and try to seek medical assistance.
Bobby Cameron, Chief of the Federation of Sovereign Indigenous Nations, pleaded with the public to release any information to the authorities if they had it.
He said: "Someone out there knows something. We beg you to come forward for the sake of the families."
The motive behind the attacks remains unknown as police continue to hunt for the remaining Sanderson brother, though drugs have been suggested.
Prime Minister Justin Trudeau added: "This kind of violence, or any kind of violence has no place in our country."
On the day of the attack, police began receiving reports of the stabbings at 5.40am in the James Smith Cree Nation community which has a population of just 3,400.
The nearby village of Weldon was also affected and has only 200 residents.
Police say some of the victims appear to have been deliberately targeted, but others were seemingly attacked at random.
