Colombia-Venezuela: Border fully reopens after years of diplomatic dispute

Cars honked and passengers in vehicles with licence plates from both countries waved flags as they crosed the Atanasio Girardot bridge, which was the final step for the full reopening of the borders since the countries restored diplomatic ties last year.
