The Twitter accounts of the Kenyan defence forces and its spokesman have been hacked by activists protesting about corruption.
One post read “All of you who have stolen money #Kenya, we are coming after you”.
The hacked posts were signed as being from activist group Anonymous.
Kenyan military spokesman Major Emmanuel Chirchir often uses Twitter to give updates of the war against Somalia’s al-Shabab militant group.
The hackers criticised the government of President Uhuru Kenyatta, saying it only protected the interests of the elite and was not doing enough.
Anonymous, a loosely-knit group, has been involved in a number of high-profile online protests and attacks in recent years.
