Hundreds of third country nationals, presumably Third World illegal migrants, entered the Athens law school on Monday to demand that the Greek government grant them permanent residency cards, a development that generated heated criticism by at least two major party-affiliated student groups.

One grouping, PASOK-affiliated PASP, in an announcement, charged that the rival leftist grouping AP.En, affiliated with the Coalition of the Left (Synaspismos), essentially herded 250 migrants inside the building in order to demand their unconditional legalisation.

PASP said the AP.En student grouping provocatively ignored a decision by the school's faculty senate last week to reject a request to "host" the migrants inside the law school.

Meanwhile, the New Democracy-affiliated DAP students' group also expressed its opposition to the "takeover", as it said, adding:

"Those responsible for this situation are members of the AP.En student grouping and groups unaffiliated with the university, ones backed by Synaspismos, who barged into the building without any approval, breaking down the interior doors and taking over the Solonos (Street) building and placing mats and other items inside," the announcement read.
