Hundreds of Jordanians have attended the funerals of nine Christians who were fatally shot during a church service last week.

Today’s funeral took place at St George's Greek Orthodox church in Karak – the same place gunmen opened fire during a funeral service in Friday’s attack, injuring around 40 people.

Eight of the victims’ coffins were wrapped in Jordanian flags before they were buried in a graveyard in the village of Hamoud, where the attack took place. Mourners and priests gathered at the scene.

Speaking from her home, from where the red dome of St George's church is visible, al-Halsa concluded that God must have saved her.

"My life starts now, because I was going to die," she said, speaking beside her husband Ziad al-Halsa. A statue of Jesus on a cross was displayed on a shelf.

Authorities have said they are still searching for the attackers, adding it was too early to determine whether they had links to known groups inside or outside Jordan.

There has been no immediate claim of responsibility.

Ziad said he ran the short distance to the church after he heard the gunfire, describing the overwhelming sense of relief when he realised Sahar, who he described as "the love of his life", was safe.

"To my cousins, may God have mercy on them," he said.

Such attacks are highly unusual in Jordan, a relatively stable state in the Middle East, though authorities there say they have foiled several Islamist plots in recent years.

Speaking ahead of the funerals, priest Yuhanna Hamati said:

"Our message from this church, from this place where this horrific crime was committed, is a message of love, peace, and reassurance. A message that we send to the whole world."

Security forces were stationed at churches across Jordan during Sunday services in a tightening of security at Christian sites.
