Nearly 300 Bulgarian university lecturers and students demanded once again Wednesday the resignation of the Socialist-led government.

The rally started at noon at the campus of Sofia University.

Then they moved to the building of the Parliament, which is guarded by riot police, and built a symbolic wall of books around the security fences.

After that, the protesters returned to the University where they briefly blocked the nearby intersection.

No incidents have been reported.

The demonstrators, however, have issued a declaration in which they say this is their last warning and in case the government of Prime Minister, Plamen Oresharski, still refuses to resign, they threat civil unrest with blockades of junctions, roads, and railroads.

They accuse the country's rules of acting anti-democratically and using police brutality to disperse peaceful rallies with which they push young people to emigrate.

The "college" protests began when students occupied Lecture Hall 272, the largest teaching room of Sofia University St. Kliment Ohridski on October 22. The occupation is now lifted and there is only a partial blockade of the building's aula.

Protesters against the Oresharski cabinet first walked out, June 14, after the appointment of controversial media mogul Delyan Peevski for head of Bulgaria's State Agency for National Security.

Peevski's reinstatement as MP after his resignation from the Security Agency provoked a student occupation at Sofia University, which culminated in Sunday's "March of Justice."

Protesters have claimed that the Oresharski cabinet, backed by the Bulgarian Socialist Party and the liberal Movement for Rights and Freedoms exemplifies in an acute form the deep influence of the so-called Bulgarian oligarchy on politics.

Rallies, although much smaller in numbers, are still held every evening in downtown Sofia.
