US President Joe Biden expressed his "sadness and outrage" over 4 separate murders of 4 Muslims in New Mexico.

The US police are investigating a possible relationship between the recent killing of 3 Muslims and the killing of another Muslim during the past year in Albuquerque, New Mexico, in the southern United States.

"I am outraged and saddened by the horrific murders of four Muslim men in Albuquerque," Biden said in a tweet on Twitter.

The US police had announced that the murder of a Muslim man last Friday evening in Albuquerque, New Mexico, may be linked to the killings of 3 other Muslims in the same city.

Biden made it clear that his administration is awaiting a full investigation into the incidents that targeted 4 members of the Muslim community in the city, the last of whom was a young man from South Asia who was killed on Saturday.

The US President expressed his solidarity with the families of the victims, saying that his administration stands firmly with the Muslim community, stressing that "there is no place for hate crimes in America."

I am angered and saddened by the horrific killings of four Muslim men in Albuquerque.

While we await a full investigation, my prayers are with the victims' families, and my Administration stands strongly with the Muslim community.

These hateful attacks have no place in America.

The US police said - in a statement - that they had found the body of the fourth dead man from South Asia, believed to be in his twenties.

Among the victims were two Pakistanis, one of whom was 27 years old when his body was found on August 1, and the other was 41 when his body was found on July 26.

Police said investigators are looking into whether these murders are linked to the November 7, 2021 killing of an Afghan man in front of a business he runs with his brother in Albuquerque.

The police called on anyone with information to call a specific phone number, noting that the FBI is assisting in the investigation.

The Council on American-Islamic Relations (CAIR), the largest Muslim civil rights organization in the United States, announced on Saturday that it had offered a reward of $10,000 to anyone who provides information leading to the arrest of the suspect.

"This tragedy affects not only the Muslim community, but all Americans," said Nihad Awad, National Executive Director of the Council on American-Islamic Relations.

"We must unite against hatred and violence, regardless of the race, religion or origin of the victims and perpetrators," he added.
