AMMAN — Mutah University students on Sunday launched a campaign to clean up the campus following three days of rioting last week, the Jordan News Agency, Petra, reported.

The students involved in the brawl, who numbered around 50, set fire to grass and wooden chairs, and also reportedly damaged science labs in the university.

The students, belonging to two tribes from Karak Governorate, 130 kilometres south of Amman, used guns, knives and stones during the riots in which seven students were injured and a professor was stabbed.

Dozens of students are participating in the voluntary clean-up campaign, which they say is intended to restore the image of their university, Petra said. 

The five-day campaign includes painting chairs, carrying out maintenance work and planting flowers and trees, according to Petra. 

Students are also expected to hold a silent vigil on Wednesday to condemn the riots and renounce violence. 

Late last week, police arrested six people allegedly involved in the riots that took place at the university and they were referred to the criminal prosecutor for questioning.

Tribal leaders in Karak, who condemned the latest incidents at the university, have called on the government to stand firmly against those responsible for the brawl and take legal action against them.
