Ispuini d'Urartu, who ruled towards the end of the 9th century BC, left a stela at Karagündüz, not far from Lake Van. On this stela he recounts a military campaign against Parsua and the city of Mesta in the country of the Manneans.

He then razed Sagbita, a royal town, which was located further north of the lake of Urmia according to the indications of the 8th campaign of Sargon published by Thureau-Dangin in 1912. After having destroyed by fire Sagbita and the villages around, Shamshi-Ramman returned to Assyria by Muçi, probably a bad spelling of Musri or Musasir.
