Authorities in Beirut seized two tons of drugs on a private jet Monday and detained a member of the Saudi royal family and four others, according to Lebanon's state-run news agency and a government official.
Smugglers were attempting to transport the "huge quantity" of Captagon pills — which essentially contain amphetamine — to the Saudi capital of Riyadh, The National News Agency said.
Monday's bust was the largest-ever smuggling operation uncovered at Beirut's Rafik Hariri International Airport, according to the news agency.
Saudi Arabia's ministry of foreign affairs did not immediately respond to NBC News' request for comment.
