Al Jazeera quoted Hariri as saying that "I will return to Beirut in the coming days. I will participate in the celebrations for our independence and it is there that I will make known my position on all the issues."
Lebanon will mark its Independence Day on Wednesday, November 22.
Earlier on Saturday, Lebanese President Michel Aoun and Speaker of Parliament Nabih Berri both posted statements saying Hariri would return for the occasion.
A statement on Aoun's official Facebook page said the president received a phone call from Hariri after his arrival in France's capital, in which the Lebanese prime minister confirmed his participation in the Independence Day celebrations.
Hariri accused Tehran of spreading chaos, strife and destruction throughout the region.
Hariri also said that Hezbollah's policies have put Lebanon "in the eye of the storm."
Hariri was appointed prime minister in late 2016 and headed a 30-member national unity cabinet that included the Shiite militant Hezbollah. (ANI)
