AKIKO FUJITA: In our worldview today, dueling missile tests are escalating tensions on the Korean Peninsula. North Korea test fired two ballistic missiles off its coast on Wednesday, marking the first test in six months. Those missiles landed within Japan's exclusive economic zone, prompting Prime Minister Yoshihide Suga to condemn the actions as a threat to peace and security in the region.

Hours later, South Korea conducted its own launch, test firing a ballistic missile launched by submarine for the first time. The dueling tests come amid stalled nuclear-disarmament talks between Washington and Pyongyang.

A major brawl reportedly broke out inside of Afghanistan's presidential palace just days after its interim government was announced. The BBC reports the argument last week centered around the Taliban victory over the US, specifically who in the group did the most. The leadership also reportedly disagreed over how power should be divided up in the new cabinet.

These reports are coming to light as rumors swirl over the fate of Taliban cofounder Mullah Abdul Ghani Baradar. Baradar hasn't been seen publicly since the first week of September, leading to the speculation he's injured or dead. The Taliban denied reports of the palace brawl.

And the World Anti-Doping Agency says it's reviewing its ban on cannabis in international athletics. The news comes months after US sprinter Sha'Carri Richardson was banned from competing in the Tokyo Olympics after she tested positive for THC in the Olympic trials. Richardson was hit with a 30-day suspension then.

WADA's executive committee says it plans to begin scientific review of the status of cannabis next year, which means the substance will continue to be banned through the 2022 season.
