Saudi security forces on Saturday killed a man who was wanted for plotting a bombing near the Prophet's Mosque last year, local media reported.
Last July, a suicide bomber detonated explosives near the mosque and burial place of the Prophet Mohammad, killing four security officers and injuring five others.
On Saturday, Saudi forces conducted a raid in capital city Riyadh, killing two suspects including one who was linked tothe bombing.

They were killed after they refused to surrender and opened fire on the police.
“They tried to escape from capture by exchanging fire with security forces that injured one officer. The two were also wearing suicide explosive belts,” Mansour Al-Turki, a spokesman for Saudi Interior Ministry, said at a press conference, al-Arabiya reported.

A Saudi security official said that al-Sayari was a scholarship student in New Zealand in the past where he majored in engineering.
He went to Syria to join ISIS fighters. He made his way to Turkey and Sudan and then to Yemen before coming to Saudi Arabia.
