KUALA LUMPUR (Sept 18): Malaysia may have to pass a law forcing its companies to tackle fires on land they control abroad, Prime Minister Tun Dr Mahathir Mohamad said on Wednesday, as forest fires in neighbouring Indonesia spread haze across the region.

Southeast Asia has suffered for years from dry-season bouts of smoke caused by fires, many in Indonesia, set to clear land, raising worries about health and the impact on tourism.
