A senior police official says a Syrian man has been arrested on Greece's northeastern border with Turkey with a large batch of telescopic sights for rifles and shoulder-fired rocket launchers.

The official, who spoke to The Associated Press on condition of anonymity because he wasn't authorized to speak to the media about the case, said he believed the weapons were headed for Syria. There has been no official announcement by police.

The arrest took place Thursday when the man, who is a resident of Belgium, crossed the border with Turkey in a tractor trailer, according to the official. Customs officials found 281 telescopic sights.

The arrested man said he re-entered Greece after Turkish customs authorities turned him back. He will appear in a Greek court Monday.
