About 250 Iranian university  students staged a sit-in in front of the U.N. office here in  protest of "the U.S.-British invasion against the oppressed Afghan nation," the official IRNA news agency reported Thursday.
The protesting students, mostly from Tehran's Imam Sadeq  University, started the sit-in Wednesday night. Protesters waved  banners that read: "The blood of the Americans is no different  from the blood of the Afghans," "The Taliban are the creation of  the United States," and  "American hands are stained with the  blood of Zionist crimes."
A representative of the students announced that they were  determined to continued the protest for 24 hours. "We strongly  condemn the massacring of the innocent Moslem civilians in  Afghanistan on the phony pretext of fighting against terrorism,"  he said.
Police sealed off the street where the UN office is located. A  police commander said the protesting students staged this "quiet  sit-in strike" without getting prior permission from the Interior  Ministry, thus the strike is "illegal."
The United States and Britain launched military strike on  Taliban targets in Afghanistan late Sunday in retaliation for the  September 11 terrorist attacks on New York and Washington.  Washington has accused the Taliban of harboring Saudi-born Osama  bin Laden, the prime suspect of the terror attacks.
Iran condemned the September 11 terror attacks, but is strongly opposed to U.S. military strikes against Afghanistan.
