The elimination of Yahya Sinwar has plunged Hamas into unprecedented turmoil, triggering a complex succession battle that highlights deep ideological rifts within the terror organization. Security analysts view Sinwar's demise as more strategically significant than the previous eliminations of Ismail Haniyeh and even Hamas founder Ahmed Yassin in 2004, primarily due to the organization's current ideological divide between pro-Iranian and Sunni Muslim Brotherhood factions.
This internal schism became evident in July following Haniyeh's elimination, when both Iran and Sinwar adamantly opposed Khaled Mashal's potential return to leadership. Mashal, known for his strong Qatar and Turkey connections, represents Hamas's Sunni wing, making him a controversial figure among the organization's pro-Iranian elements.

The power struggle intensified as Hamas attempted to maintain operational continuity while selecting new leadership. Israel's security establishment assesses that the organization's decision-making center may shift from Gaza back to its overseas leadership, marking a significant strategic realignment.
A critical factor in this succession battle is the control over Israeli hostages, currently managed by Mohammed Sinwar, the eliminated leader's brother, who operates alongside Rafah Brigade commander Mohammed Shabana. This leverage has strengthened the Gaza-based leadership's position in internal deliberations.
The Iranian axis within Hamas has rallied behind several key figures:
- Khalil al-Hayya, who formally announced Sinwar's elimination, coordinates hostage negotiations from Qatar and recently met with Iranian Foreign Minister Abbas Araghchi in Istanbul.
- Mohammed Darwish, heading Hamas' Shura Council, maintains strong Tehran ties.
- Mohammed Sinwar's control over hostages and combat operations in Gaza makes him a formidable contender.
Countering this Iranian influence, the Sunni axis presents its own candidates:
- Khaled Mashal, despite his contentious relationship with Iran, leverages his extensive diplomatic connections with Qatar, Turkey, and Pakistan. His recent suggestion of Iranian involvement in Haniyeh's elimination underscores the deep divisions within Hamas's leadership.
- Moussa Abu Marzouk, with his strong Muslim Brotherhood credentials, continues to shape the organization's diplomatic messaging.
The appointment of Mohammed Sinwar as chief negotiator for hostage deals and de facto Gaza commander signals a potential consolidation of power within the Iranian-aligned faction. While this role doesn't automatically translate to overall Hamas leadership, it positions him prominently in the succession race. However, his reported reluctance to negotiate hostage deals from a position of perceived weakness reflects Hamas's complex internal dynamics and could impact both the organization's future direction and the broader conflict's trajectory.
