Kim's Daughter Named Heir; Activists March in Venezuela

North Korean leader Kim Jong Un has reportedly chosen his teenage daughter, Kim Ju Ae, as his heir, according to South Korea's spy agency, while in other international developments, a top US antitrust official resigned amid tensions, Mexico sent humanitarian aid to Cuba, emboldened activists took to the streets of Venezuela, and Canadian authorities investigated a school shooting suspect's home.

The National Intelligence Service (NIS) of South Korea informed lawmakers on Thursday that Kim Jong Un had selected his daughter, believed to be 13 years old, as his successor. The NIS cited her increasing presence at official events, including a visit to Beijing in September, as a factor in their assessment, according to BBC World.

In the United States, Gail Slater, the top official responsible for antitrust enforcement at the Department of Justice (DOJ), announced her resignation on Thursday. Appointed last year by former President Donald Trump, Slater's departure has sparked concerns that the White House is backing away from anti-monopoly enforcement, as reported by BBC Business. "It is with great sadness and abiding hope that I leave my role," she wrote in her announcement.

Meanwhile, in Canada, authorities investigated the home of a teenage suspect involved in a school shooting after receiving multiple calls regarding mental health concerns and weapons, The Guardian reported. Firearms were seized from the residence approximately two years prior but were later returned. Six people, including a teacher and five children, were killed in the shooting.

Mexico sent humanitarian aid to Cuba on Thursday, with two navy ships arriving in Havana laden with supplies, according to The Guardian. This action comes as Mexico navigates a delicate diplomatic situation with the United States.

In Venezuela, protesters took to the streets in cities across the country, demanding the release of political prisoners, The Guardian reported. This follows the recent downfall of Nicolás Maduro, with student demonstrators gathering at the Central University of Venezuela in Caracas.
