The incident involved Nominated MP Umulkheir Harun Mohammed (Umi) and East African Legislative Assembly (EALA) MP Falhada Iman.
A video captured the two MPs exchanging blows within Parliament grounds. Several colleagues intervened to stop the fight.
The exact cause remains unclear, but Umi attributed it to long-standing differences with Iman, although details were withheld.
Both MPs hail from Garissa County, Kenya. Umi is affiliated with ODM, while Iman is affiliated with UDA. The possibility of deeper political rivalry is raised.
