Jordanian authorities have arrested three suspects in connection with a deadly attack on a Greek Orthodox church in the village of Hamoud, in the Karak governorate, approximately 120 kilometres southwest of Amman.

Armed men stormed St George's Church during a funeral procession on Friday, killing nine people and wounding at least 34 others. Authorities described the attack as carried out by "extremist terrorists".

The three suspects were arrested during a dawn raid on Monday after a gun battle that lasted approximately three hours in the village of al-Jadeeda, a short distance from Hamoud. They had been hiding in an abandoned house and refused to surrender, attacking security forces before being subdued.

All three sustained injuries during the operation. One was reported to be in a critical condition. Security forces recovered firearms and ammunition at the hideout.

Jordan's Interior Minister Mazin al-Farrayeh confirmed that all three suspects are Jordanian nationals. He said they "were identified early on in the wake of the terrorist incident, and the security services employed all the means at their disposal to apprehend them".

He added that they "put up fierce resistance against the security forces, but were ultimately subdued and taken into custody, having sustained severe injuries".

Public Security Director Major General Obaidullah al-Maaytah identified the suspects at a Monday news conference, saying they belong to the same family and include two brothers. "They are the two brothers Hazza, the planner and mastermind, and Mishal Zeidan Muhammad, and their relative Ahmed Sami Hussein," he said.

Al-Farrayeh said there was no indication that the arrested suspects have ties to other cells. He also said the perpetrators represent only themselves.

Multiple locations were raided during the search operation before the suspects were surrounded and arrested in the final operation, the minister said.

Al-Farrayeh said investigations into the attack are ongoing. "Everyone who has been part of this terrorist act will be taken to justice," he said.

The Public Security Directorate stated that "terrorism has no place among us" and that the suspects had met their "just fate".

Security camera footage of the attack circulated online following the incident. Video broadcast by a Jordanian television channel showed three individuals shooting outside the church and running towards its entrance. Other footage showed the attackers opening fire on a group of men attempting to flee the building.

St George's Church is located in Hamoud, in the Karak governorate, a region known for its medieval-era castle.

Jordan's King Abdullah II ordered security forces to respond with an "iron fist" to what was described as an unprecedented attack on the country's Christian minority community. During a National Security Council meeting on Saturday, the king said: "The security and safety of Jordanians are a red line … the hand of justice will reach every terrorist."

Al-Farrayeh, in a post on social media on Monday, said: "We have apprehended the killers, we are examining all the circumstances that lead young people towards extremism, and we will hold accountable everyone found to have been involved."

He called on citizens to remain calm and said the tragedy would result in practical measures to protect civilians, urging Jordanians to reject violence.

The three suspects are due to be brought before the courts. Jordan retains capital punishment.
