Kiram's proof why Sabah is his family's

Sulu Sultan Jamalul Kiram III shows documents to Yahoo! Southeast Asia to prove that his family is the rightful owner of the disputed areas in Sabah.

Among the documents are "receipts" from the Malaysian government as proof that the Malaysia is just paying rent for their land. He also shows letters from Malaysia addressing him as the rightful heir of the Sultanate of Sulu.
