Hundreds of protesters clashed with police in riot gear Saturday outside a remote immigration detention center in southern Australia.

About 400 protesters converged on the Baxter Immigration Detention Center near the city of Port Augusta on Friday as part of a weekend-long demonstration against Australia's illegal immigrant detention policy. They attempted to get past a strong police cordon at the rear of the facility today but were pushed back.

At least three people have been arrested for trespassing.

The protesters are demanding an end to the government's controversial policy of mandatory detention for illegal immigrants.

In a separate demonstration Friday, about 300 protesters gathered outside the home of Australia's immigration minister, Amanda Vanstone, near the city of Adelaide.
