A cement truck toppled over in Naxxar yesterday, critically injuring its 24-year-old driver. The victim, from Mosta, was taken to Mater Dei Hospital after Civil Protection Department personnel released him from the cabin. It appears the heavy vehicle hit the pavement in Margret Murray Street. Writing on a Facebook group of local traffic updates, a person said she saw the truck flip on its side after turning the corner. No other cars were involved.
