- Iran and Russia reportedly signed a secret €500 million missile deal in December 2025, according to the Financial Times.
- The pact covers delivery of 500 Verba man portable air defense launch units and 2,500 9M336 missiles through 2027 to 2029.
- The Verba systems are infrared guided MANPADS designed to target low altitude threats including drones and cruise missiles.
- The deal follows damage to Iran’s air defense network during the 2025 conflict with Israel.
- The agreement reflects deepening military cooperation between Tehran and Moscow.
US Investigation Finds Likely US Responsibility In Iran School Strike
A US investigation into the Iran school strike has reportedly found preliminary evidence suggesting that a US weapon may have been responsible for the attack, according to sources familiar with the probe cited by Reuters.
The strike, which hit a school building in Iran during the ongoing escalation linked to the Israel Iran conflict, caused civilian casualties and quickly drew international attention. Early assessments from investigators are said to indicate that the damage pattern and fragments recovered at the site are consistent with a US manufactured munition.
US officials have not yet publicly confirmed the findings, emphasizing that the investigation remains ongoing and that a final determination has not been released.
Incident Raises Questions Over Military Operations
The Iran school strike investigation emerged as fighting across the Middle East intensified in recent weeks, with Israel conducting strikes on Iranian military infrastructure and the United States increasing its regional military posture.
According to sources briefed on the matter, US investigators reviewed imagery, strike data, and fragments believed to have been recovered from the attack site. Preliminary technical analysis reportedly suggested the possible involvement of a US produced weapon system.

However, officials cautioned that multiple actors operate similar equipment in the region, complicating efforts to determine exactly which platform or operator carried out the strike.
Reuters reported that investigators were examining whether the munition could have been launched during coordinated operations linked to the broader conflict environment.
Civilian Casualties Increase Scrutiny
The US responsibility Iran school strike issue has triggered renewed scrutiny of civilian harm during high intensity military operations in densely populated areas.
Schools, hospitals, and other civilian infrastructure are protected under international humanitarian law. When such sites are struck, investigations typically focus on whether the location was misidentified, whether intelligence was flawed, or whether a weapon malfunction occurred.

Defense analysts note that modern precision guided munitions significantly reduce but do not eliminate the risk of unintended civilian casualties. Factors such as targeting data errors, electronic interference, or changes in battlefield conditions can affect strike outcomes.
If the investigation confirms that a US weapon was involved in the Iran school strike, it could raise broader questions about operational coordination and accountability during the rapidly evolving conflict.
Technical Analysis Underway
Military investigators often rely on forensic analysis of weapon fragments to determine the origin of a strike. Components such as guidance systems, tail kits, and fuse assemblies can sometimes be linked to specific munition families.
In cases involving US produced precision weapons, analysts typically examine signatures associated with widely used systems such as Joint Direct Attack Munition kits, laser guided bombs, or other precision strike weapons.
Satellite imagery and radar tracking data may also help reconstruct the flight path of the munition and identify the launch platform, whether an aircraft, drone, or missile system.
Experts say the US investigation Iran school strike process could take weeks or months before reaching a final conclusion.
Strategic Context In The Israel Iran Conflict
The investigation comes amid one of the most volatile phases of the Israel Iran confrontation in years. Israeli forces have reportedly targeted Iranian military infrastructure across several regions, including command centers, missile sites, and logistics facilities.
The United States has also increased naval and air defense deployments in the region, including guided missile destroyers equipped with advanced missile defense systems.
The presence of multiple allied and partner forces operating in overlapping airspace complicates the operational picture. Defense analysts say that crowded battlespace environments increase the risk of misidentification and unintended strikes.
For Washington, the outcome of the US responsibility Iran school strike investigation could have diplomatic implications as tensions continue to rise across the Middle East.
Investigation Still Ongoing
US officials have stressed that the Iran school strike investigation remains preliminary. Authorities are continuing to analyze battlefield data, munition fragments, and operational logs.
Until the investigation concludes, officials say no definitive attribution has been made.
However, the case illustrates the complex challenges facing military forces operating in modern high intensity conflicts where advanced precision weapons, electronic warfare, and dense urban environments intersect.
