Bangladeshi students are demanding answers and action after a military training jet crashed into their school, killing at least 31 people.

Hundreds of students gathered outside the smouldering remains of a school in the Bangladeshi capital on Tuesday to demand answers after a military jet slammed into the campus, killing dozens of children.

More than 170 people were injured after the training aircraft crashed, military officials said. The country’s interim leader called the loss “irreparable.”
