An 11-year-old boy crashed a pickup truck into a group of monks on a pilgrimage walk in northeastern Thailand on Thursday, killing eight, officials said.

A total of 35 monks from Mukdahan province, about 600 kilometers northeast of the capital Bangkok, were on the pilgrimage.

Five monks were killed at the site, while three others died at a hospital, according to Mukdahan Governor Worrayan Boonnarat. Fourteen others were hospitalized, with four in critical condition.

The group started the 260-kilometer walk to Ubon Ratchathani province about 30 minutes before the crash.
