A tornado that killed two people in the Texas city of Van this week caused about $40 million in damage and flattened scores of buildings, emergency officials said on Thursday.

More than 500 structures suffered some damage from the EF3 category tornado packing winds of around 225 km per hour that hit Van, a city west of Dallas, on Sunday night, the officials told a news conference.

About 90 houses were destroyed, Van Zandt County Fire Marshal Chuck Allen said. Van has a population of about 2,500.
