Thousands of students in the northern Ethiopian region of Amhara have walked out of the national school-leaving exams that determine their entry to universities.
Over 12,000 high school students refused to sit the exams, according to official figures.
A statement by the education ministry has not provided any reason for their refusal but it comes as authorities introduce new measures to curb what they called a rampant epidemic of cheating.
Exam leaks have become common in recent years.
To limit the cheating, the government this year moved students – more than 500,000 in the first round alone – to different university campuses around the country. They were to be confined in the campuses for the exam period and prohibited from accessing mobile phones and the internet.
A second round of exams, for hundreds of thousands of students, was due to start on Thursday.
Amid the new measures, a student was killed and some security forces were injured when violence erupted after students tried to stage a walkout in Amhara.
Another student had died earlier when a bridge collapsed in a university campus in the country’s south.
The exams are not taking place in the war-torn region of Tigray, where the federal government has not provided education for two years.
