 Diodotus, in the name of the boy-king Antiochus VI, controlled most of Inland Syria, including Antioch, Apamea, Larisa and Chalcis.Demetrius on the other hand based himself in Seleucia Pieria and retained control of many of the Syrian and Phoenician coastal cities and Cilicia.Mesopotamia continued to recognise Demetrius as well and an invasion of the region by Diodotus in mid-144 seems to have been a failure.
