MADRID (AP) — A Spanish judge has reopened a probe into the suspected spying on the cellphone of Spain’s prime minister after receiving a request to collaborate with a similar investigation in France.

The judge with Spain’s National Court said Tuesday there is reason to believe that the new information provided by France can “allow the investigations to advance.”

Both probes concern the alleged use of Pegasus spyware developed by the Israeli NSO Group. The spyware silently infiltrates phones or other devices to harvest data and potentially spy on their owners. NSO asserts that it is only made available to governments for fighting terrorism and other security threats.

Pegasus has been used to target more than 1,000 people across 50 countries, including activists and journalists, according to security researchers and a 2021 global media investigation.
