At least 10 lions died in Kenya in the past week, as per Kenya Wildlife Service.

According to reports, six lions died on Saturday.

This is “an unusually large number of lions to be killed at one go,” a spokesperson for the KWS told CNN on Sunday.

It comes after conservationists announced the killing of one of Africa’s oldest lions, Loonkiito, at the age of 19 earlier this week.

He had ventured out of a protected area and into a livestock pen due to being “starving,” and was killed by the livestock owner, according to conservation organization Lion Guardians, as reported by CNN.
