I want to know the answer to the following question:
The Seleucids invaded Mesopotamia under whose guidance?
All the background I'm provided with is that "The Seleucid–Parthian wars continued as the Seleucids invaded Mesopotamia under Antiochus VII Sidetes (r. 138–129 BC), but he was eventually killed by a Parthian counterattack.". Is that enough to answer the question?
