A homemade, remote-controlled bomb intended to "kill or to harm" riot control officers was detonated as they deployed against renewed violence in Hong Kong over the weekend, police said Monday, in a further escalation of destructive street battles gripping the business hub. The "loud thud" Sunday night close to riot officers who had been clearing away a protester-built road block marked the first known use of an explosive device during protests that started in June over a contested extradition bill and have snowballed into an anti-government, anti-police and anti-China movement. "It exploded less than 2 meters (yards) away from a police vehicle. We have reason to believe that the bomb was meant to target police officers," Deputy Commissioner Tang Ping-keung said at a news conference, speaking through a translator. Get More

Syrian government troops moved into towns and villages in northeastern Syria on Monday, including the flashpoint region of Manbij, setting up a potential clash with Turkish-led forces advancing in the area as long-standing alliances in the region began to shift or crumble following the pullback of U.S. forces. The Syrian military's deployment near the Turkish border came after Syrian Kurdish forces previously allied with the U.S. said they had reached a deal with President Bashar Assad's government to help them fend off Turkey's invasion, now in its sixth day. Assad's return to the region his troops abandoned in 2012 at the height of the Syrian civil war is a turning point in Syria's eight-year civil war, giving yet another major boost to his government and its Russian backers and is like to endanger, if not altogether crush, the brief experiment in self-rule set up by Syria's Kurds since the conflict began.

A handful of states are celebrating their first Indigenous Peoples Day on Monday as part of a trend to move away from a day honoring Christopher Columbus. From Minnesota to Vermont, at least five states and Washington, D.C., have done away with Columbus Day celebrations in deference to Native Americans, though the federal Columbus Day remains in place. Since 1992, Native American advocates have pressed states to change Columbus Day to Indigenous Peoples Day over concerns that Columbus helped launched centuries of genocide against indigenous populations in the Americas.

Rescue crews on Sunday searched for a worker missing in the partial collapse of a New Orleans hotel that was under construction, their work proceeding cautiously amid fears about the stability of the structure, authorities said. Officials declined to say if they have any indication whether the missing worker is alive after Saturday's collapse. New Orleans Fire Chief Tim McConnell said they are treating their work as a rescue mission until they have evidence the missing person is dead along with two other people killed when a large part of the Hard Rock Hotel project crashed down near the city's historic French Quarter. "Safety is the No. 1 thing. The last thing you want to do when you are trying to rescue somebody is lose someone else," McConnell said at a news conference Sunday. Get More
