At the time of her disappearance, Ms Peet was understood to have last contacted a friend on 8 February, saying she was in São Paulo and planned to travel to Rio de Janeiro. She had not been heard from since.Days later, her UK-based family told the friend they had lost contact with her and provided authorities with details of her flight and a copy of her passport to aid the search.

According to her LinkedIn profile, Ms Peet has worked as a freelance journalist in Rio and London for organisations including Al Jazeera and The Times.Ukraine's Security Service (SBU) says it has managed to strike the Crimea bridge with underwater explosives following an operation lasting "several months".The SBU said its agents had "mined the supports" of the bridge with 1,100kg of explosives which "severely damaged" the bottom level of the supports.

The "first explosive device" was activated early Tuesday morning "without any civilian casualties", the SBU added.The information shared by the SBU could not be immediately verified.

Russian media initially said the bridge was briefly closed to traffic but that it had reopened by 10:00 local time (08:00 GMT).

However, on Tuesday afternoon, local authorities warned the bridge was closed again. Unconfirmed reports on social media said more explosions had occurred around the structure.Mwangi said his "abduction" was shocking in how brazen it was as he had been "picked from a very prominent hotel".

"So having been abducted during broad daylight and never knowing where I was, and I was still tortured, means that the Tanzanian government doesn't care about what people think about it," he told the BBC.Earlier, Atuhaire said that despite Uganda being "very dictatorial", she did not imagine she "would find a worse foreign country, a worse government".

Mwangi said their experience showed "how broken" countries in East Africa were."So it makes me more of a pan-African in this fight," he told the BBC.
