After a speeding bus struck and killed two students in Dhaka, Bangladesh, their peers began to pour into the streets to demand justice.
Since then, tens of thousands of students, many dressed in school uniforms, have essentially shut down the capital, blocking roads and preventing transit through much of the city.
They're calling for improvements to road safety in Bangladesh, where around 12,000 people are killed in road accidents each year.
As the protests grew in recent days, students stopped vehicles - including those belonging to government officials - to ask them for their papers and licenses.
Some buses have been vandalised and set on fire, including one that was set ablaze after it hit and killed a motorcyclist on Friday.
