Saudi Arabia's Shiite minority prepared a mass funeral today for the victims of a mosque bombing that authorities described as an attempt by Sunni extremists to sow sectarian strife.
Organisers said they expected huge crowds to turn out in the mainly Shiite Qatif district of Eastern Province to show their respects for the 21 dead, who included two children.
Everybody "is very much anxious to participate... To express their support," one organiser said, asking not to be named.
Last Friday's suicide bombing, during the mainly weekly Muslim prayers in Kudeih village, was the second mass killing of Shiites in the kingdom since late last year.
In November, gunmen killed seven Shiites in the Eastern Province town of Al-Dalwa.
Asked whether he feared a new attack during the funeral, the organiser said, "Nobody can predict anything. We have taken all precautions in coordination with local authorities."
He added that tens of thousands of people had volunteered to act as crowd marshals for the three-hour ceremony.
He said safety concerns had prompted organisers to ask women to stay away from the funeral but that a separate area had been set up for them to offer condolences after the burials.
The Islamic State group said it carried out the bombing, the first time the jihadists, who control swathes of neighbouring Iraq and Syria, had claimed an attack in the Sunni-dominated kingdom.
The interior ministry confirmed that the bomber, a Saudi national, had links with ISIS, which considers Shiites heretics.
It was the deadliest attack in years in Saudi Arabia and King Salman vowed on Sunday that anyone with the slightest involvement in the "heinous crime" would be punished.
Most of the kingdom's Shiites live in the east, where the vast majority of the kingdom's oil reserves lie but where Shiites have long complained of marginalisation.
Saudi Arabia and its Sunni Gulf neighbours joined a US-led air campaign against ISIS in Syria last year, raising concerns about possible retaliation in the kingdom.
