Iran International
Regional reactions to the appointment of Mojtaba Khamenei as Iran’s new Supreme Leader have revealed growing anxiety about stability, with Tehran’s allies condemning the killing of his father and adversaries hardening their military posture.
Khamenei Jr’s continued absence from public view has fueled speculation among analysts and diplomats about how power is being exercised during the transition.
The message read on his behalf on state television on Thursday was viewed by some observers as closely aligned with the Revolutionary Guards (IRGC) messaging, prompting questions about the balance between formal leadership and the IRGC.
As expected, Tehran’s regional non-state allies in Iraq, Yemen and Lebanon have rallied around the new leader, calling him the “Leader of the blessed Islamic Revolution.” His ascendence to power is perceived by these armed groups as continuity in funding and weapons transfers.
Not many share this view in the region and beyond.
Arab neighbors
Across the Persian Gulf, Mojtaba’s appointment has been met with a mix of defensive military posturing, criticism, and calls for closer security coordination.
Tensions with Saudi Arabia rose sharply after his appointment when an Iranian strike hit a Saudi residential area. Prior reporting in US media, including The Washington Post, indicated Riyadh had privately urged Washington to use significant military force to prevent Iran from emerging stronger after the transition.
Elsewhere in the region, Tehran and its proxies have been blamed for strikes on civilian infrastructure—including a desalination plant in Bahrain.
Arab League Secretary-General Ahmed Aboul Gheit denounced Iran’s “reckless policy,” reflecting broader anxieties among smaller Gulf states.
Reactions from Qatar, Kuwait and the United Arab Emirates have reflected concern about escalation, as the leadership transition coincided with direct attacks on regional infrastructure.
Turkey
In Turkey, President Recep Tayyip Erdogan struck a supportive tone, calling Iranian officials “brothers” and expressing hope they would “get through this trap-filled period.”
Ankara has also criticized US strikes and appears likely to maintain pragmatic engagement with Iran’s leadership to avoid instability along its borders.
Russia, China and the EU
Russia’s President Vladimir Putin was among the first to respond, calling Ali Khamenei’s death a “cynical murder” and describing him as an “outstanding statesman.” His message to President Massoud Pezeshkian emphasized solidarity with Iran during the transition.
China adopted a more cautious tone, stressing respect for Iran’s sovereignty and opposing regime change. Chinese officials framed the succession as a constitutional matter and an internal Iranian process.
The European Union’s reaction has been more fragmented. Diplomats say some member states quietly hope the transition could open space for political change, while others fear instability could widen the conflict. Publicly, EU officials have emphasized de-escalation regardless of who leads Iran.
None of the three powers aligned with Tehran as the United Nations condemned IRGC-linked attacks on regional targets this week.
Israel
Israel was the only country in the region to explicitly question the legitimacy of Mojtaba’s appointment, describing it as a continuation of what it called the IRGC’s “terror regime.”
Even before the appointment, Defense Minister Israel Katz wrote on X that “any leader appointed to continue the plan to destroy Israel will be an unequivocal target for elimination.”
Public reactions across Iran and parts of the Arab world have been mixed. Some early expressions of relief at Ali Khamenei’s death gave way to concern about escalation as Mojtaba’s ties to the IRGC came into focus.
Across the region, officials and analysts say the leadership transition has reinforced fears that an already volatile conflict could widen further in the weeks ahead.
For days the conflict had focused largely on military bases, missile sites and command facilities, particularly in southern Iran, as part of the wider US-Israeli campaign that has struck thousands of targets across the country since the war began on February 28.
But since Wednesday evening, reported drone strikes on checkpoints in Tehran have pointed to a parallel line of pressure: the local security posts, patrol units and temporary deployments used to enforce control on the streets.
Iranian state-linked media said several checkpoints in Tehran were hit, killing members of the security forces and Basij militia. The reported locations included positions in multiple districts across the capital.
The development suggests the conflict is increasingly intersecting with the structures the state relies on to control neighborhoods rather than only its larger military infrastructure.
From fixed bases to moving checkpoints
Since the start of the war, residents across Iran say checkpoints and patrols have multiplied in major cities as authorities attempt to prevent unrest and maintain control.
At the same time, Iran International has received a steady stream of messages from viewers describing the locations of checkpoints, security deployments and temporary bases.
Some reports describe armed units inspecting vehicles at major highway entrances or intersections. Others mention security forces using schools, sports halls and religious institutions as temporary accommodation or staging points.
Messages received in recent days pointed to deployments in locations ranging from major Tehran highways to entrances to cities such as Karaj, Shiraz, Mashhad and Qazvin. Residents also described units stationed beneath highway bridges, near parks or inside parking areas where buses and motorcycles were parked overnight.
In several cases, viewers reported that checkpoints they had previously seen disappeared within hours or days, while others appeared to move to nearby streets or disperse into smaller patrol groups.
Some messages described security forces sleeping inside buses or personal vehicles and conducting mobile patrols rather than remaining in fixed positions.
Others said checkpoints that had been inspecting vehicles were suddenly dismantled, leaving only a few officers nearby.
Such reports cannot be independently verified in each case. But taken together they suggest that many deployments are becoming more fluid, with positions shifting frequently rather than remaining in one place.
A war over control of the neighborhood
The shift reflects a deeper pressure on the state’s local enforcement network.
For years the Islamic Republic has relied on a dense web of Basij, police and Revolutionary Guards positions to control neighborhoods and quickly suppress unrest.
During the recent nationwide protests earlier this year, these same networks formed the backbone of the crackdown that sealed off districts and quashed the demonstrations.
In wartime, those local security units appear to be playing an even more central role.
As larger bases and installations come under pressure from airstrikes, authorities appear to be relying more heavily on mobile checkpoints and temporary deployments to maintain control on the ground.
Now those fallback positions are also being drawn into the conflict.
The result is a battlefield that increasingly overlaps with everyday urban space. Instead of remaining confined to distant military facilities, the war is beginning to touch the street corners, highway entrances and neighborhood patrol routes where the state exerts day-to-day authority.
