12 out of 19 people arrested over bomb attacks are Pakistanis, says Saudi Arabia

Saudi Arabia officials have stated that 12 out of 19 people arrested over Monday's bomb attacks in the country are from Pakistan.

An Interior Ministry spokesman also named a suicide bomber who killed four security officers near a mosque in the sacred city of Medina as Naer Muslim Hamad, a 26-year-old Saudi man, who had a history of drug abuse.

Three people who allegedly carried out attacks in Qatif were also named as Abdulrahman al-Omar (23), Ibrahim al-Omar (20) and Abdulkarim al-Husni (20).

The ministry said none of them had Saudi IDs. The attacks in Qatif took place on the same day and were also suicide bombings.

No group has claimed responsibility for the attacks yet but they are suspected to have been the work of people with allegiances to Islamic State.
