The case has stirred public opinion since the discovery on Tuesday of the first nine bodies near the village of Baakline in the Chouf area southeast of Beirut, in what Prime Minister Hassan Diab described as an "appalling crime."
The victims fell ill after consuming the liquor on Monday night and were taken to a hospital, where three of them died, Udai Bhanu Tripathi, a district magistrate, told Reuters, adding that two more died en route and 19 were being treated.
The case in the mountainous northern region of Kohistan has attracted international attention since it first emerged in 2012, when a local cleric was accused of ordering the deaths of male and female guests filmed at a wedding.
The video showed the security personnel rushing in just in time to save the woman after she lost balance and fell on the platform.
The media said that the device was dismantled and defused by a bomb disposal squad.
“With Saudi Arabia, we have made commitments towards Lebanon: to work together, to support reforms, to enable the country to emerge from the crisis and preserve its sovereignty,” Macron said on Twitter.
