In a dramatic escalation of tensions, North Korea blew up the liaison office used to improve relations with South Korea on Tuesday. And, in a move to stop a flare-up of new coronavirus cases, Beijing has imposed restrictions on public transport and banned high-risk people, such as those in close contact with others who have tested positive for COVID-19, from leaving the city. Also, three Indian soldiers were killed today in a confrontation with Chinese troops in the disputed border region of Kashmir.
