Missile fragments found at site of strike on girls' elementary school in Minab, Iran, bear US insignia, The New York Times (NYT) reports.

Analysis of the fragments indicates that they are most likely parts of an American Tomahawk cruise missile, which is exclusively in service with the US military.

According to NYT, the investigation materials include verified videos and satellite photos that show the missile flying over the area of the Iranian naval base and hitting a school in the immediate vicinity of the base.

NYT experts note that only the US has this type of cruise missile, and this casts doubt on the initial official statements of the American leadership that the US had nothing to do with the attack on this school.

At the same time, the NYT is considering the version that the school was not targeted intentionally, but was damaged as a result of an attack on a nearby Iranian naval base.

Earlier, US President Donald Trump claimed that Iranian forces could be behind the attacks on the school, categorically denying the Pentagon's involvement. However, on the same day, the White House confirmed that the incident is already being investigated by the US Department of War.

The February 28 strike on the aforesaid school was one of the deadliest incidents in the US-Israeli military campaign against Iran, killing about 170 people, most of them children.
