Captain Ali bin Abdullah al-Qahtani, the border guard spokesman, said
Sunday that 49 of those arrested were drug smugglers carrying more than
800 kilograms (1,800 pounds) of hashish.
Faisal bin Khaled bin Abdul-Aziz, the governor of the southwestern
province of Asir, which borders Yemen, said Saturday that most of the
infiltrators in his region are from Ethiopia, Chad and Somalia.
In the past, Saudi Arabia has reported blocking several infiltration
attempts by militants from Yemen's al-Qaida branch to carry out attacks
inside the kingdom.
