British authorities are launching a criminal investigation into the London apartment building fire — as the death toll from the blaze has nearly doubled, to 30.

The death toll is expected to rise further as rescue workers continue to search for victims – an operation that Metropolitan Police Commander Stuart Cundy described as "extremely challenging."

Hundreds of people gathered in St. Paul, Minn., Friday evening to protest a verdict that found a Minnesota police officer not guilty on all counts in his deadly shooting of a black man during a traffic stop in 2016.

Demonstrators gathered at the Minnesota State Capitol holding signs that included the phrases "black lives matter," and "no justice, no peace," and hundreds marched toward the nearby Cathedral of Saint Paul.

An advertising blimp fell from the sky on Thursday and crashed near the scene of golf's U.S. Open in Wisconsin, injuring the pilot.

The Washington County Sheriff's Office described the pilot's injuries as "serious." It said in a statement that the pilot was the only person on board.

"The initial investigation reveals the blimp may have experienced mechanical problems prior to the crash," the sheriff's office added.

Video of Turkish security personnel appearing to punch, kick and club demonstrators in Washington, D.C., went viral and sparked outrage last month.

Now, the Metropolitan Police Department has announced that 18 people are facing charges in connection to the incident outside the Turkish ambassador's residence during a visit by Turkish President Recep Tayyip Erdogan.

A federal judge in Washington, D.C., ruled Wednesday that the Trump administration failed to follow proper environmental procedures when it granted approval to the controversial Dakota Access Pipeline project.

It's a legal victory for the Standing Rock Sioux tribe and environmentalists, who protested for months against the pipeline. Oil started flowing through it earlier this month. The tribe fears that the pipeline, which crosses the Missouri River just upstream of its reservation, could contaminate its drinking water and sacred lands.
