More than 62 body fragments belonging to 32 students martyred in a US airstrike on an Iranian elementary school have been identified through DNA testing and buried, nearly five months after the attack that killed 168 people, most of them children.

The remains, recovered during weeks of search operations at the Shajareh Tayyebeh School in Minab and surrounding areas, were carried through the streets of Hormozgan province in a funeral procession Wednesday before burial at the city's martyrs' cemetery.

Grieving parents and other citizens gathered earlier at the site where coffins were prepared to bid a final farewell to what remained of their children.

Mojtaba Qahramani, head of Hormozgan's judiciary, said that despite multiple specialized search operations at the school and its environs, no trace has been found of 7-year-old Makan Nasiri, a first-grader who remains the only victim whose body has never been recovered.

Qahramani told the Fars news agency that the US missile struck directly at the location where Makan was standing at the moment of impact.

An empty grave has been prepared for Makan, while his personal belongings including a bloodstained sweater and a single sneaker are preserved in a glass display case at a nearby mosque.

His parents have spent months searching for any sign of their son. "Where am I supposed to look for my son?" his father asked in an interview earlier this year, his eyes filled with tears.

The Feb. 28 strike on the Shajareh Tayyebeh School occurred on the first day of the US-Israeli military aggression against Iran and is considered the terrorist war's deadliest attack on civilians.

Iranian officials put the death toll at 168, including 120 students and 26 teachers. More than 110 people were wounded.
