A former student allegedly used a knife to attack dozens of students at a college in Yixing, China, and cause eight deaths and wound 17 others Saturday evening.

Earlier this week, a 62-year-old man killed 35 people and wounded more than 40 more when he rammed his small SUV into a crowd in the southern city of Zhuhai. The suspect was discovered in the car with a knife, with wounds to his neck thought to be self-harm injuries, according to the police.
