A resolution adopted unanimously by the council today renewed the sanctions it authorised last year until February 26, 2016.
That means the asset freeze and travel ban remain in place against ex-president Ali Abdullah Saleh and Houthi leaders Abd al-Khaliq al-Huthi and Abdullah Yahya al Hakim.
The crisis in the impoverished country has escalated in the wake of the power grab by the Houthis, who are believed to be backed by Saleh.
