Police in the Netherlands say they have found narcotics in a truck Thursday that was part of a convoy carrying aid to victims of the earthquake that rocked Turkey and Syria. 

Authorities did not give details of what kind of drugs or the quantity, but said they were hidden among emergency supplies. 

The drugs have since been destroyed, and the five other trucks in the convoy are being scanned before being allowed to proceed.  

No arrests were immediately made. Police said they received a tip that the drugs were on board.
