Swedish climate campaigner Greta Thunberg is fined for disobeying police at a rally last month, but says she acted out of necessity due to the climate crisis. "The laws need to be changed," she tells reporters. The 20-year-old appeared in court in the southern Swedish city of Malmo after 11 am (0900 GMT). The activist "took part in a demonstration that disrupted traffic" and "refused to obey police orders to leave the site", according to the charge sheet seen by AFP. IMAGES AND SOUNDBITES
