BEIRUT, Lebanon (AP) _ The Lebanese army said today it rescued two Germans from a cave in southern Lebanon. A German official said the same couple may have sought help from the German Embassy in July.

The army said the husband and wife entered Lebanon in January 1990 and had been missing since then. The army communique broadcast by state-run Radio Lebanon identified the Germans as Jurd Schiller, 49, and Inge Burroek, 34.

''A Lebanese army force managed after a search to find them in a cave in the south,'' the statement said. The army statement said the couple had been held, but did not identify their captors.

In Bonn, a government official said the couple may be the same people who came to the German Embassy in Lebanon in July claiming they had been kidnapped. The official, who spoke on condition of anonymity, said that couple - who identified themselves as Gerd and Ingeborg Schletter - had no papers and no money and wanted to return to Germany. The official said the embassy was unable to verify that the couple had been kidnapped.

There had been no public report that a German husband and wife were missing in Lebanon.
