Jordanian authorities are searching for three gunmen responsible for Friday's deadly shooting at a Greek Orthodox church in Hamoud, Karak governorate, as investigators seek to establish their identities and motive.
The attack killed eight people and injured 40 others, according to officials, prompting heightened security measures and a nationwide period of mourning.
The shooting occurred during a funeral service when three attackers opened fire inside and around the church.
Witnesses reported hearing what initially sounded like an explosion before gunfire continued for several minutes.
Survivor Nasser al-Burqan told Reuters that an attacker pointed a handgun at him from approximately two metres away and fired.
His son was subsequently hospitalised with a gunshot wound to the leg.
Authorities confirmed that seven victims died at the scene, while another succumbed to injuries hours later.
Of the 40 injured, 27 remained hospitalised, including one patient in critical condition following surgery.
Security footage broadcast by Al-Mamlaka reportedly showed three individuals firing outside the church before approaching its entrance.
Authorities have not identified the suspects or established whether they have connections to extremist organisations.
No group has claimed responsibility.
King Abdullah II visited Karak following the shooting and ordered a review of security procedures for responding to terrorist attacks.
Security was subsequently reinforced at shopping centres, foreign embassies and other locations across Jordan.
Prime Minister Jafar Hassan attributed the violence to extremist ideology without identifying a specific organisation or establishing a motive.
He also declared three days of national mourning, with flags lowered across government and public buildings.
The attack has shaken Karak's Christian community, which forms part of Jordan's estimated 300,000 Christians among a population of 11.5 million.
Azerbaijan, Iraq, Poland, Palestine and Qatar condemned the shooting, while the United States embassy expressed condolences.
Al-Azhar's grand imam, Ahmed al-Tayeb, also denounced the attack.
The investigation continues as authorities pursue the unidentified gunmen and seek to determine what motivated the deadly assault.
