BEIRUT, Jan. 12 (Xinhua) -- Lebanon's Caretaker Economy Minister Raed Khoury Saturday said that any measure against the invitation of Libya to take part in Beirut Summit "is not in the interest of Lebanon," local media reported.

"Inviting Libya to Beirut summit is very normal," Khoury was quoted as saying by Elnashra, an online independent newspaper.

Khoury represents the Free Patriotic Movement (FPM) which was originally established by President Michel Aoun.

Aoun has confirmed a few days ago that the summit will be held on time without commenting on the debate over inviting Libya to the summit.

Ali Khreis of the Amal Movement, a Lebanese Shiite political party, said on Friday that the Libyan delegation will be forbidden from entering Lebanon to attend the Arab Economic and Social Development Summit scheduled for later this month.

A day earlier, the Amal Movement announced a plan to launch nationwide protests to close the airport ahead of the summit in a bid to prevent the Libyan delegation from taking part in the event.

Lebanon has been accusing Libya of being responsible for the disappearance of Musa al-Sadr, the most prominent and charismatic Shiite voice in the decade before the outbreak of the Lebanese civil war in 1975.

Al-Sadr disappeared alongside Sheikh Muhammad Yaacoub and the journalist Abbas Badreddine during an official visit to Libya in August 1978.
