It urged Tanzania to "expeditiously and without delay" allow access, or release him, "in accordance with international legal obligations and diplomatic norms".Later, Kenya's state-funded rights commission said it had received the activist in Kwale county, following his release from Tanzania.KNCHR posted a picture of him alongside other people including his wife, Njeri, and fellow activist Hussein and said he was "in high spirits". The commission said it was planning to transfer him to the capital Nairobi for medical attention.

The activist was reportedly left at the Kenyan border on Thursday morning following his release by the Tanzanian authorities.On Wednesday, his wife told the BBC that she had last heard from him on Monday and had not been able to establish where he was.

"I'm actually concerned for his life. I know my husband, he would have communicated, he'd find a way to call or text me and because he hasn't, makes me very worried about what state he is in," she told the BBC Newsday radio programme.

Kenya's foreign ministry on Thursday expressed similar concerns about the activist's "health, overall well-being and the absence of information regarding his detention".Both the army and the RSF have been accused of war crimes, which they deny.
