Kenya demands release of activist Boniface Mwangi from Tanzania

By Newsflash Writer

NAIROBI, Kenya – The Government of Kenya has formally protested the continued detention of Kenyan activist Boniface Mwangi by Tanzanian authorities, citing violations of international diplomatic protocols and expressing alarm over the lack of communication and transparency surrounding his case.

In a strongly-worded diplomatic note dated May 21, 2025, the Ministry of Foreign and Diaspora Affairs of Kenya addressed the Ministry of Foreign Affairs and East African Cooperation of the United Republic of Tanzania, demanding immediate consular access to Mwangi.

The letter, referencing Mwangi’s passport number BK 472892, calls for the Tanzanian government to facilitate either his release or, at minimum, access by Kenyan consular officials.

The Ministry notes that despite several attempts to obtain information and provide consular assistance to Mwangi, Tanzanian authorities have continued to deny Kenya’s requests. The lack of updates concerning Mwangi’s condition and whereabouts has raised serious concerns within the Kenyan government.

“The Ministry is also concerned about his health, overall wellbeing and the absence of information regarding his detention,” the letter reads.

In the official protest note, Kenya invokes the Vienna Convention on Consular Relations (1963), to which both countries are signatories. The Ministry highlights Articles 36(a) and 36(c) of the Convention, which guarantee the right of consular officers to communicate with and visit nationals of the sending state who are in detention.

According to the Convention:

Consular officers must be free to communicate with nationals of their country and must be granted access to them;
Nationals under detention have the right to contact and receive assistance from their consular officers;
Consular officers also have the right to visit detained nationals, converse with them, and arrange legal representation.

Kenya emphasized that the denial of access is a breach of these legally binding obligations.

Diplomatic frustrations

“In light of the above,” the letter states, “the Ministry of Foreign and Diaspora Affairs respectfully urges the Government of the United Republic of Tanzania to expeditiously and without delay facilitate consular access to or release of Mr. Mwangi, in accordance with international legal obligations and diplomatic norms.”

The note reflects growing frustration within Nairobi over what it sees as a disregard for diplomatic protocol and mutual respect between the two East African neighbors. Kenya’s government reaffirmed its commitment to maintaining cordial relations with Tanzania but underscored that such cooperation depends on adherence to international agreements.

The Ministry concluded its communication by expressing hope that the matter would be “resolved swiftly and amicably,” reiterating the need for regional cooperation and mutual respect.

As of the time of writing, Tanzanian authorities have not publicly responded to Kenya’s diplomatic note. It also remains unclear what charges, if any, Boniface Mwangi faces in Tanzania or the circumstances under which he was apprehended.

Mwangi, a well-known Kenyan photojournalist, activist, and human rights defender, has been an outspoken critic of social injustice and corruption across the East African region. His detention is likely to raise public interest and potentially strain diplomatic relations between the two countries if not addressed promptly.

Kenya’s demand for immediate access to its citizen signals a diplomatic escalation and reaffirms its stance on protecting the rights of its nationals abroad. It also sends a message to neighboring states about the seriousness with which Nairobi treats violations of international law and agreements.
