Residents of the northeastern Thai city of Nakhon Ratchasima are grieving after Thailand suffered its worst mass shooting Saturday. A soldier killed at least 29 people and injured scores more during a 16-hour rampage. The gunman began his shooting spree on a military base before taking to the streets, then attacking shoppers at a mall. He was eventually shot and killed after a shootout with Thai forces. The shooter posted videos of the attack on Facebook Live; the videos and his account were later removed.
