State media said three people were killed and 79 injured by an explosion at a train station in Urumqi in the restive Xinjiang region. Police cordoned off the station, but it has since reopened. Railway stations in China were busy due to the start of a four-day holiday. President Xi had been concluding a four-day visit to Xinjiang, and it is not clear if he was in the region at the time of the blast. While there, he said that Kashgar is in the front line of the battle against terrorism and the situation is “grim and complicated.”
