A truck transporting gas bottles overturned and exploded - unleashing an inferno - in Worcester in the Western Cape on Wednesday morning.

Western Cape transport and public works spokesperson Ntomboxolo Somdaka tweeted that the explosion happened in High Street.

It was reported that two firefighters and one other person were injured in the blast.

The Breede Valley municipality said on Facebook on Wednesday morning the following roads are closed in Worcester:

The exit from the N1 to the suburb of Meirings Park; High Street; Smit Street; Field Street; Brown Street; and Church Street. “This is as a result of a gas truck that exploded in the area. The public is encouraged to make use of other routes‚ reduce speed and exercise caution.”

This is a developing story.
