A rare fire tornado has been seen in the Brazilian state of Sao Paolo. A whirlwind of flame, spiralling several metres high, danced across burning fields, bringing traffic to a halt on a nearby highway. This unusual phenomenon has been caused by a combination of wildfires and strong dry winds following weeks of drought in the country. Authorities in Brazil are struggling to contain the fires and have banned farmers from burning waste from the sugar cane harvest.
