Turkish authorities seized a truck en route to Syria that was carrying weapons Thursday and three people were arrested in the incident, according to Agence France-Presse.
The truck was stopped in Turkey's southern province Hatay that shares a border with Syria.
The drivers said they were "carrying aid on behalf of the pro-Islamic Humanitarian Relief Foundation, IHH." IHH, however, has called the incident "slanderous" and said that it has nothing to do with the case.
Turkish media say that approximately 47 tons of weapons have been sent to Syrian rebels via Turkey since June.
Turkish government authorities have denied sending weapons directly from the government to the rebels despite their open support of the opposition.
Approximately 600,000 Syrian refugees have fled to Turkey for refuge.
