+                positions they had initially occupied when they launched a new offensive near the southern port of 
+                Basra early yesterday.     A High Command communique said Iraqi troops had won a significant victory 
+                and were continuing to advance.     Iraq said it had foiled a three-pronged thrust some 10 km 
+                (six miles) from Basra, but admitted the Iranians had occupied ground held by the Mohammed al-Qassem 
+                unit, one of three divisions attacked.     The communique said Iranian Revolutionary Guards were under 
+                assault from warplanes, helicopter gunships, heavy artillery and tanks.     "Our forces are continuing 
+                their advance until they purge the last foothold" occupied by the Iranians, it said.     
+                (Iran said its troops had killed or wounded more than 4,000 Iraqis and were stabilising their new positions.)     
+                The Baghdad communique said Iraqi planes also destroyed oil installations at Iran's southwestern Ahvaz field 
+                during a raid today. It denied an Iranian report that an Iraqi jet was shot down.     
+                Iraq also reported a naval battle at the northern tip of the Gulf. Iraqi naval units and forces defending an 
+                offshore terminal sank six Iranian out of 28 Iranian boats attempting to attack an offshore terminal,
