Around 20 tons of cannabis in 25 trucks were seized on Sunday in the Bekaa region of eastern Lebanon, a security services official told AFP.
"Twenty-five lorries carrying about 20 tons of cannabis were seized on Sunday at Deir al-Ahmar" as part of an anti-drugs operation launched on Thursday by the security services, the official said.
Three other vehicles loaded with a total of more than two tons of drugs were seized on Saturday in the same operation, along with equipment for processing hashish, he said.
Several people have been arrested, the official added.
The Bekaa Valley has long been known as fertile territory for narcotics, which flourished into a multi-billion dollar industry during the Lebanese civil war from 1975-1990.
Illegal cultivation diminished for a while but has expanded again in recent years after the failure of alternative crop programs.
The number of eradication campaigns has expanded but people in charge of destroying illicit plants are often threatened by traffickers.
