The Canadian government is facing pressure to declare a national day of mourning after the bodies of 215 children were found in British Columbia on the grounds of a school for Indigenous children who were forcibly separated from their families by the government. The bodies were discovered at the Kamloops Indian Residential School, which opened in 1890 and closed in the late 1970s.

A major new report on police killings suggests far more people of color have died in police custody than previously known. The report by the Raza Database Project and UnidosUS found that deaths of Latinos, Asian and Indigenous peoples have been historically undercounted. Researchers documented the deaths of 32,542 people who have been killed by police since 2000, 60% of whom constitute people of color, who make up just 40% of the U.S. population.

Democratic lawmakers in Texas staged a dramatic walkout to prevent the Republican-controlled Legislature from passing a sweeping bill to rewrite election laws in the state. Critics say the bill will lead to mass voter suppression, especially of Black and Latinx voters, by eliminating drive-thru and 24-hour voting, as well as ballot drop boxes. The Republican bill would also make it easier for elections to be overturned even if there is no evidence of fraud.

Memorial Day marks the 100th anniversary of the 1921 Tulsa race massacre, one of the deadliest episodes of racial violence in U.S. history, when the thriving African American neighborhood of Greenwood in Tulsa, Oklahoma — known as “Black Wall Street” — was burned to the ground by a white mob. An estimated 300 African Americans were killed and over 1,000 injured. Whites in Tulsa actively suppressed the truth, and African Americans were intimidated into silence.

As the United Nations human rights chief warns Israel may have committed war crimes in Gaza, we look at how Israel killed 12 Palestinian children being treated for trauma from past Israeli bombings. Jan Egeland, secretary general of the Norwegian Refugee Council, says Gaza has become “the home of hopelessness,” particularly for young people in the besieged territory.
