IRAN SAYS HAS BETTER WEAPONS THAN SILKWORM Iranian Prime Minister Mir-Hossein Mousavi said Iran had "more effective" missiles at its disposal than the shore-to-sea missiles which had provoked U.S. Concern, Tehran Radio reported. A U.S. State Department spokesman said last week Iran had acquired Chinese-made Silkworm missiles which posed a greater threat to shipping in the Gulf than the weapons previously used. Tehran Radio, monitored by the British Broadcasting Corp, quoted Mousavi as saying that Tehran officially announced after its forces overran southern Iraq's Faw peninsula in February last year that it had shore-to-sea missiles. "The fact that the Americans, after so much delay, are now thinking of expressing their concern with panic is because Reagan needs this sensation now," said Mousavi, speaking after a cabinet meeting in Tehran. "We also announce today that these missiles are not the limit of our war capabilities in the Gulf," he added. Mousavi said the security of the Gulf region had nothing to do with the U.S. But Iran would resort to any action to defend the Gulf, "even those actions which are not thought probable by Westerners."
