Seven people, including four children, died Monday when strong winds from a rainstorm caused a metal roof on a school`s activity center to collapse in northern Thailand, officials said Tuesday.

The latest casualty was a 6-year-old boy who died late Monday night in a hospital after the collapse at the Wat Nern Por primary school, according to the public relations office in Phichit province, 300 kilometers (185 miles) north of Bangkok.
