Access to the social media platform X has been restricted in Tanzania after some official accounts of government and private institutions were targeted by hackers.

On Tuesday, the official police account was compromised, with sexually explicit material and false information that the president had died being posted.

The police dissociated itself from the information and said an investigation was under way to identify those responsible.

Hours later data from the internet monitoring organisation Netblocks showed that X was “unreachable on major internet providers” across the country.

Users in Dar es Salaam, the country’s biggest city, could still not access the site on Wednesday although some people in other regions indicated they were able to log on.

Information Minister Jerry Silaa acknowledged the hacking and assured MPs in parliament that the affected government social media accounts had since been secured.

Earlier, government spokesman Gerson Msigwa warned the people responsible that immediate action was being taken.

The problems with accessing X come amid the continued uproar over the deportation of prominent Kenyans – a move that prevented them from attending the court case of opposition leader Tundu Lissu, who is accused of treason.

On Monday, the president warned activists from its northern neighbour that she would not allow them to “meddle” in her country’s affairs and cause “chaos”.

She spoke after Kenya’s former Justice Minister Martha Karua along with some others, who had all travelled to attend Lissu’s court case, were deported.

Another Kenyan activist, Boniface Mwangi, and Ugandan Agather Atuhaire were arrested in Dar es Salaam by suspected military officers on Monday and their whereabouts remain unknown.
