IRANIAN teachers warned they had reached a crisis point as they demanded the release of trade unionists detained during strike action and protests over wages, terms and conditions today.

Co-ordinating Council of Iranian Teachers’ Trade Associations (CCITTA) spokesman Mohammad Habibi condemned the arrest of Ahmad Heidari and others in front of the parliament building in the capital Tehran.

Three teachers, Mohammad Ali Zahmatkesh, Asghar Amirzadegan and Ghahraman Kiani, were also held following protests in Shiraz on Monday, he said.
