Explainer: What's behind the standoff between Ukraine's two intelligence agencies?

Key Points:

• A violent shootout on Sept. 2 between Ukraine's Security Service (SBU) and military intelligence agency (HUR) exposed deep dysfunctions, including a long-standing conflict between the two agencies and allegations of unlawful methods used by intelligence personnel.
• The incident involved the alleged illegal detention and psychological pressure on Stepan Kaplunov, a deputy commander of the Russian Volunteer Corps affiliated with HUR, with conflicting accounts from the SBU and Kaplunov regarding the events leading to the shootout.
• Political analysts and insiders suggest the confrontation may be part of internal power struggles, possibly aimed at undermining Kyrylo Budanov, Zelensky's Chief of Staff and former HUR head, amid ongoing factional disputes within Ukraine's intelligence community.
• The acting head of the SBU, Oleksandr Poklad, has been criticized for a controversial management style and alleged involvement in prior contentious operations, raising concerns about a culture of lawlessness within Ukraine's security services.
• These incidents highlight broader issues of accountability and coordination within Ukraine's law enforcement and intelligence agencies, which remain critical yet contentious components of the country's defense amid the ongoing war.
