Saudi Arabia has executed 37 Saudi citizens across the country for alleged terrorism-related crimes.
In mass executions the Saudi nationals were beheaded after which one headless body was publicly pinned to a pole to warn off others.
The executions come days after four Islamic State gunmen died trying to attack a Saudi security building north of the capital, Riyadh.
It follows Easter Day attacks that killed over 300 people in Sri Lanka and were claimed by the Islamic State group.
The state news agency said in a tweet: "The death penalty was implemented... on a number of culprits for adopting extremist terrorist ideologies and forming terrorist cells to corrupt and disrupt security as well as spread chaos and provoke sectarian strife."
Saudi Arabia's Interior Ministry said Tuesday's executions were carried out in accordance with Islamic law, using language that indicated they were all beheadings.
The body of one of the men was publicly pinned to a pole for several hours in a process that is not frequently used by the kingdom and has sparked controversy for its grisly display.
The statement did not say in which city of Saudi Arabia the public display took place.
The government defends such executions as a powerful tool for deterrence.
The Interior Ministry statement said those executed had adopted extremist ideologies and formed terrorist cells with the aim of spreading chaos and provoking sectarian strife.
It said the individuals had been found guilty according to the law and ordered to be executed by the country's high court.
The individuals were found guilty of attacking security installations with explosives, killing a number of security officers and cooperating with enemy organisations against the interests of the country, the Interior Ministry said.
It comes a day after the Islamic State group said it was behind an attack on Sunday on a Saudi security building in the town of Zulfi in which all four gunmen were killed and three security officers were wounded.
Executions are traditionally carried out after midday prayers.
Public displays of the bodies of executed men last for around three hours until late afternoon prayers, with the severed head and body hoisted to the top of a pole overlooking a main square.
The executions marked the largest number in a single day in Saudi Arabia since January 2016, when the kingdom executed 47 individuals, including a prominent Shiite cleric whose death sparked protests in Iran and the ransacking of the Saudi Embassy there.
