Morocco's government on Wednesday threatened legal action against anyone accusing it of using the Israeli spyware programme Pegasus, and deplored what it called a "false, massive, malicious media campaign".
A government statement "categorically denied the false and unfounded allegations" that the North African country's intelligence services had used the software.
The authorities said a judicial inquiry to identify those behind the accusations was being opened.
News outlets had reported on Sunday that the software, developed by Israeli firm NSO Group, had been used by governments to spy on activists, journalists, lawyers and politicians around the world.
The bombshell claims were based on a leaked document containing 50,000 numbers of people identified as potential targets via Pegasus between 2016 and June 2021.
Numbers from 10 countries – Azerbaijan, Bahrain, Hungary, India, Kazakhstan, Mexico, Morocco, Rwanda, Saudi Arabia and the United Arab Emirates – figured particularly often on the list.
On Monday, Morocco said it had "never acquired computer software to infiltrate communication devices".
French newspaper Le Monde reported the next day that President Emmanuel Macron and members of his government were among the potential targets, allegedly due to the interests of a Moroccan security agency.
Also on Tuesday, Radio France had reported that the Moroccan king was on the list of 50,000 numbers, which also included "a large number" of Moroccan royals.
Wednesday's statement by the Moroccan government said it would "opt for a judicial process, in Morocco and internationally, against any party taking up these spurious allegations".
The public prosecutor said in a later statement: "A judicial inquiry is being opened into these false allegations and accusations in order to identify the parties responsible for their publication."
