Internet access was disabled in East African nation Sudan ahead of nationwide protests slated for Thursday to press for civilian rule.
Internet monitoring organisation Netblocks reports that internet access was disrupted across the country at 08:00 local time (06:00GMT).
For days, the protesters have been using social media platforms to organise.
Reports indicate that security forces closed major bridges linking the capital, Khartoum, to the twin cities of Omdurman and Bahri ahead of the protests.
A Sudanese doctors’ union said 103 people had been killed as a result of the crackdown against pro-democracy demonstrations prompted by last year’s military coup.
