The United Nations Human Rights Commission has called for quick and thorough investigations into the killing of 11 Kenyans during the Saba Saba Day demonstrations on July 7.

The UN High Commissioner for Human Rights, Volker Türk, in a statement on Tuesday afternoon, termed yesterday's killings as 'deeply troubling' as it comes barely a fortnight after the death of 11 other protesters during the June 25 demonstrations.

In particular, Türk expressed concerns over the use of lethal ammunition, rubber bullets, tear gas, and water cannons against peaceful protesters in Nairobi and 16 other regions.

According to him, the use of lethal force by the police should only be applied when strictly necessary to protect life from an imminent threat.
