The Sudanese government has closed a newspaper that has been campaigning for the country to be divided on a north-south basis.
Al Intibaha, was "suspended indefinitely" because of its sympathy for the south's separatist movement.
Other newspapers said articles about conflicts in the south had also been blocked, and national security officers had warned them they would resume daily censorship of publications.
Southerners are six months away from a referendum on whether they should split away as an independent nation.
Analysts say most southerners favor independence but President Omar Hassan al-Bashir, leader of the main party in the north, has promised to campaign to persuade southerners to vote for unity.
Bashir lifted newspaper censorship in the run-up to April's elections, but editors have complained it has made a comeback since the poll.
