WASHINGTON, (Reuters) – Seven predominantly Black schools were evacuated in Washington due to bomb threats. They were later cleared by authorities, which included a school threatened on Wednesday during a U.S. vice president Kamala Harris visit.

Police in the District of Columbia said that threats had been made to four high schools, and three charter schools.

Washington police later declared Dunbar High School, where Harris’ husband, Douglas Emhoff, was rushed to safety https://www.reuters.com/world/us/us-vice-presidents-husband-ushered-out-event-after-reported-security-threat-2022-02-08 after Tuesday’s bomb threat, and the others “cleared with no hazardous material found.”

The bomb threats were not linked to any race by authorities. Police also said that Tuesday’s attack did not seem targeted at Emhoff who was in Dunbar as part of Black History Month.

But the incidents have further raised fears among Black communities already rattled https://www.reuters.com/world/us/more-us-black-colleges-universities-receive-bomb-threats-2022-02-01 by a series of bomb threats made last week to at least a dozen historically Black colleges and universities, or HBCUs, nationwide.

Harris released a statement saying that Americans have the right of safety at school, work and houses of worship. Harris stated that violence must be stopped in all communities.

The FBI is investigating the threat to HBCUs, but no explosives were discovered. Washington police said this week that they were investigating the threats made to Dunbar High School, which is considered the country’s first black high school.

Lewis Ferebee D.C. Public Schools Chief stated: “These incidents are serious and we take them very seriously.” He also said that the school system would continue to provide support for school communities during the ongoing (police) investigation.
