French diplomatic sources said in New Delhi that Paris has conveyed its deep concern to Pakistan over the release of Saeed whose outfit was listed as a terror group by the Sanctions Committee of the UN.
They said France and India will continue their "relentless" efforts to combat terrorism, and enhancing cooperation to deal with the menace will be an important aspect of French President Emmanuel Macron's visit New Delhi in early 2018.
In a strong reaction, India on Friday expressed outrage over Saeed's release, calling it an attempt by Pakistan to mainstream proscribed terrorists and a reflection of its continuing support to non-state actors.
On Saturday, the US also demanded immediate re-arrest and prosecution of Saeed, warning Islamabad that there would be "repercussions" for bilateral ties if it fails to take "decisive action" against the notorious terrorist.
The banned JuD head, who carries a $10 million American bounty on his head for terror activities, walked free on Friday after the Pakistan government decided against detaining him further in any other case.
He was under house arrest since January this year.
