Algeria has blocked Facebook and other social networks in an attempt to stop people cheating in exams.

The country has taken the decision to cut off access to social networks after papers and exam questions were leaked online. The decision comes ahead of the beginning of retakes of some important exams after they were already leaked, and the government said that it had taken the decision so that people would no longer be able to share leaked papers.

Earlier this month, police arrested dozens of people in an attempt to find out how parts of high school exams had made it onto social media.

People are unable to access sites including Facebook and Twitter over both normal internet connections and 3G services.

In a statement Sunday, the Ministry of Post and Information and Communication Technology said that the "cut of social networks has a direct relationship with the matriculation exams" which begin Sunday. It said that it had made the move to protect students from “phony topics” that were being circulated online.

Officials said that it had taken the decisions because the papers being circulated were false and so would give students the wrong impression.
