The siege of Queli (Georgian: ყველისციხის ალყა) was the last major military engagement during the Sajid invasion of Georgia in 914. The 28-day-long siege resulted in pyrrhic Muslim victory and execution of the Georgian commander Gobron. Despite the important victory, the invaders were unable to maintain a strong foothold in western Georgia and were forced to withdraw.
