Journalist Margaux Benn: Attacks happened in two neighbouring provinces

A Taliban assault on checkpoints killed 22 troops, officials said Sunday, as at least 50 Afghan security forces surrendered to the militants and around 100 tried to flee to neighbouring Turkmenistan after heavy fighting in Afghanistan’s northwest. The battles mark the latest setbacks for the country's battered security forces, who come under daily attack and have suffered staggering casualties in recent years. The attacks have continued even as the Taliban have been holding direct negotiations with the United States aimed at ending the 17-year war, with both sides citing progress.
