Twenty-two people are killed in clashes between Afghan civilians and Pakistani military forces. Fifteen people died and 80 others injured in Kandahar after Pakistani soldiers attacked civilian areas, while seven people were killed and 31 others injured in Pakistan when a crowd trying to enter Afghanistan became unruly and attacked military installations. The Afghan government warns of action if Pakistan "continues its rocket attacks", while the Pakistani military says it opened fire in self-defense, returning fire to the Afghan side.
