French riot police have reportedly entered the Sorbonne university in Paris to end an occupation by students protesting against an employment reform. Earlier there had been intense clashes outside between demonstrators and police. The students occupied parts of the building after breaking through police lines to force their way in.University administrators had indicated they might ask police to evict the students barricaded inside. It is the first time the Sorbonne has been occupied since student riots in 1968. The unrest is part of growing protests against new legislation making it easier for companies to fire workers under the age of 26. The centre-right government says the measure will give employers flexibility and stimulate recruitment.
