BEIJING, Jan 24 (Reuter) - China has achieved much success in fighting unrest in Tibet but police need to strike harder at those who harbour aims of autonomy, the Tibet Daily said in an edition seen in Beijing on Friday.

Officials and police should use the nationwide "Strike Hard" anti-crime campaign launched by Beijing last year to step up the fight against autonomy seekers bent on causing destruction and unrest in the region, the January 16 edition of the newspaper said.

"We must make solving big cases, chasing fugitives, striking at gangs, seizing illegal guns, bullets and explosive materials and working on prominent public safety problems a major part of 'Strike Hard'," it said.

Authorities have ordered a security clampdown in the Tibetan capital of Lhasa after a Christmas Day bomb rocked the city, causing widespread damage but no casualties.

The regional government has offered a reward of one million yuan ($120,000) for information leading to the arrest of those responsible for the blast.

Officials should integrate the fight against those seeking Tibetan independence whom Beijing says are led by the exiled god-king the Dalai Lama with regular police action against criminal activity, it said.

"We must...stitch together the anti-infiltration and anti-sabotage struggles and totally crush the splittist plots of the Dalai Lama clique," it said.

The Dalai Lama, who won the Nobel Peace Prize in 1989 for his non-violent campaign to win autonomy for his homeland, fled into exile in India in 1959 after an abortive uprising aginst communist rule.

Anti-Chinese unrest has erupted sporadically in Tibet since communist troops marched into the region in 1950. Several small bombs have been set off in Lhasa in the last two years.

China has arrested hundreds of thousands of people and executed more than 1,000 in recent months as part of its ongoing "strike hard" crackdown on crime.
