Kazakhstan's upper house of parliament has refused to consider a plan to send servicemen to join NATO-led forces in Afghanistan.
The Majilis, or lower house, in May voted to send four servicemen to join the International Security Assistance Force (ISAF).
In a rare instance of seeming discord between the two chambers, the senators returned the bill to the Majilis, saying it should be considered at a joint session of parliament.
No former Soviet Central Asian republic has so far sent any contingent to join the ISAF.
