The Iran men’s national team wore black armbands and posed with school rucksacks as the national anthem played before a match with Nigeria to remember the victims of a strike on a primary school in Iran’s Minab on the first day of the war, AFP reports.

Before kick-off in their friendly fixture against Nigeria in the Turkish town of Belek on Friday, the Iran players, including former FC Porto and Inter Milan striker Mehdi Taremi, held pink and purple school bags with ribbons on them.

Iran lost the match 2-1.

The New York Times has reported that the preliminary findings of a US military investigation indicate that a US Tomahawk cruise missile hit the school due to a targeting mistake.
