Diplomatic fallouts are expected after it emerged that Rwanda was allegedly spying on some African countries and individuals in an international espionage expose.

Revelations by the Pegasus Project report shows that Rwanda allegedly listed, for potential surveillance, mobile numbers of South African President Ramaphosa, Burundi Prime Minister Alain-Guillaume Bunyoni as well as some high-ranking Ugandan political and military figures, including then Prime Minister, now presidential advisor, Ruhakana Rugunda.

Prominent Democratic Republic of Congo politicians Jean Bamanisa Saidi, Albert Yuma and Lambert Mende are also revealed as targets.

A spokesperson for the Rwandan government denied using the Pegasus malware, telling a UK publication that the country “does not use this software system and does not possess this technical capability in any form.”

The Pegasus Project is an international investigation initiative by a consortium of more than 80 journalists from 17 media organisations including the Guardian. Investigations identify Kigali as one of the governments, including some authoritarian African regimes that are clients of Israeli spyware firm, the NSO Group.

Kigali is said to have contracted the NSO Group and selected thousands of political activists, journalists, foreign politicians and diplomats as candidates to infect their mobile phones with spyware named Pegasus.

Ugandan intelligence supremo Joseph Ocwet, Dr Ruhakana Rugunda and Sam Kutesa who were the country’s Prime Minister and Foreign Affair Minister, respectively, until recently, also had their phones allegedly tapped by Rwanda.
