(BRUSSELS) - Four Tibetan protesters were arrested and two injured in Brussels on Tuesday as anti-riot police broke up a violent protest at the Chinese mission to the European Union, police said.

Around 200 exiled Tibetans gathered outside the building in central Brussels to protest against a Chinese crackdown on protests in Tibet.

Some hurled projectiles at the building, an AFP photographer witnessed. Some 50 anti-riot police pushed back the crowd several times and used pepper spray on the protesters before making the arrests.

One of the Tibetans succeeded in jumping over the wall of the Chinese mission building and was later seen, clearly slightly injured, being taken away in a police car.

Police said he was taken to a local hospital for treatment and that another protester was also injured and hospitalised.

A police spokesman said the trespasser had been apprehended by staff inside the diplomatic mission.

Later calm returned to the scene though a police cordon was maintained around the building keeping the remaining protesters at bay.

"We want the EU to facilitate talks, China doesn't want to talk with the (Tibetan spiritual leader) Dalai Lama but if the EU made talks a priority that would help," Tenzin Yoenyi, a senior figure in the Tibetan community in Belgium, told AFP.

Some of the protesters stamped on a large red sheet, symbolising the Chinese flag.

The crowd denounced the upcoming summer Olympics in Beijing as "the games of death".

Earlier, the protesters staged a peaceful but noisy demonstration in front of the EU buildings in Brussels, calling for EU aid for Tibet.

Shouting "Wake up European Union," the protesters, waving Tibetan flags and wearing "Free Tibet" headbands, called for an EU mission to be sent to investigate the recent violence in their Himalayan homeland.

Chinese authorities have responded to the unrest with a virtually total lockdown of Tibet and other areas of China with large Tibetan populations.

The Dalai Lama said Tuesday he would resign as leader of Tibet's exiles if unrest in his Himalayan homeland worsened, as aides said a Chinese crackdown had claimed 19 more lives.

EU officials have ruled out a boycott of the prestigious games. On Tuesday a European Commission spokeswoman repeated that line, and urged the Chinese authorities not to use force against peaceful demonstrators.
