Flags have been lowered across the country to memorialize the most recent victims of a mass shooting incident.

President Donald J. Trump on Saturday evening issued a proclamation ordering American flags to be lowered to half-staff to honor the 11 people killed earlier that day at Tree of Life Synagogue in Pittsburgh. Flags are to remain lowered, the proclamation continued, until sunset Wednesday, October 31. 

A suspect was quickly apprehended and charged following the 20-minute attack during Sabbath services, shortly before 10 am. 

The Anti-Defamation League called the attack, which injured six additional people, the deadliest attack on the Jewish community in American history. Four of the wounded, according to the AP, were police officers who responded to the scene. 

Three separate congregations were conducting Sabbath services in different areas of the large building, according to Michael Eisenberg, the immediate past president of the Tree of Life. The Pennsylvania attorney general’s office said it was told by victims that a brit milah — a ritual circumcision ceremony at which a baby boy also receives his Hebrew name — was also taking place, though law enforcement officials later said no children were among the dead or wounded.

Governor Dannel P. Malloy on Sunday announced that — in accordance with the Presidential proclamation — US and state flags in Connecticut will fly at half-staff beginning immediately until sunset on Wednesday, October 31.

Accordingly, since no flag should fly higher than the US flag, all other flags, including state, municipal, corporate, or otherwise, should also be lowered during the same duration of time.
