Dubai: Two days after two suspected Al Qaida militants blew themselves up after being trapped inside a government building in southern Saudi Arabia, three shells landed in northern Saudi Arabia. No casualties were reported.

According to media spokesperson of Saudi Border Guards, the shells landed in a residential complex in Arar at 1.30pm.

Arar is located near the border with Iraq where the Baghdad government is fighting the militants who are holding territory they seized in northern and west of the country.

Meanwhile, Al Qaida in the Arabian Peninsula (AQAP) claimed responsibility for Saturday’s attack on the Saudi border post and released photographs of their preparation for the terrorist attack, Al Arabiya News website reported.

The images, which appeared to be still grabs from a video, show the faces of some militants and the launching of a Grad missile toward a border crossing between Saudi Arabia and Yemen.

In one of the pictures, the militants are being trained by a Yemeni militant leader in a desert area. One of two militants who blew themselves up on Saturday at a Saudi security building appears in another picture, smiling and carrying a Kalashnikov. He is known as Ayoub Al Suweid, and has been on an interior ministry’s wanted list for the past two years, the website reported.
