London, Aug 13 - Nepal's former prime minister Pushpa Kamal Dahal Prachanda has left for Belarus after telling supporters in London his Maoist party in Nepal is certain to usher in 'world revolution'.

'The twenty-first century will be the century of world revolution,' Prachanda told a large gathering of supporters at a meeting in south-east London.

'We in Nepal are trying to develop new strategies and tactics. We cannot mechanically repeat the strategies and practices of the Russian and Chinese revolutions.

'We are confident that we will lead the (Nepali) revolution to success,' he declared at the meeting organised by the Nepali Samaj - a sister organisation of the opposition Unified Communist Party of Nepal (Maoist), of which Prachanda is chairman.

At one point during the meeting at Woolwich town hall Monday, Prachanda told a questioner about the 'ongoing struggle in eastern India against a series of mining multinationals in the tribal areas', and said NGOs and INGOs (international non-government organisations) 'confuse the masses'.
