There was a heavy police presence at the Milimani Law Courts ahead of the sentencing of three suspects charged in the September 21st, 2013 Westgate Mall terror attack.
Hussein Hassan Mustafah, Liban Abdullah Omar and Mohammed Ahmed Abdi, are set to be sentenced on Tuesday afternoon.
Chief Magistrate Francis Andayi found the three guilty and a fourth accused Adan Dheq being set free in January 2019 after the prosecution failed to prove a case against him.
The trio faces 12 counts linked to the commission of a terrorist act, conspiracy to commit a terrorist act, giving support to a terrorist group and being in the country illegally.
More than 145 witnesses testified against the accused persons.
The attack on September 21, 2013, in the upscale Nairobi mall left 67 people dead and several others wounded.
Terror group Al-Shabaab, which is based in Somalia, claimed responsibility for the attack that caused a four-day siege.
