SALT LAKE CITY — President Barack Obama has ordered the lowering of the flag of the United States of America to half-staff as a mark of respect for the victims in a nightclub shooting in Orlando, Sunday.

The flags are to be lowered June 12 and expected to stay at half-staff until sunset, on June 16. Utah Gov. Gary Herbert issued a similar statement for the flag of the state of Utah and the American Flag in Utah for the same timeline.

The mass shooting at the gay nightclub left 50 dead and at least 53 injured, according to Orlando police. The shooting is considered the deadliest terrorist attack on U.S. soil since 9/11.

I also direct that the flag shall be flown at half-staff for the same length of time at all United States embassies, legations, consular offices, and other facilities abroad, including all military facilities and naval vessels and stations. IN WITNESS WHEREOF, I have hereunto set my hand this twelfth day of June, in the year of our Lord two thousand sixteen, and of the Independence of the United States of America the two hundred and fortieth.
