"Following the substantial destruction of ISIL's energy infrastructure it is critical to remain vigilant against its efforts to increase previously minor income streams, or to cultivate new ones. One of the new sources is drugs trafficking in Afghanistan, especially in the northern provinces, which ISIL is trying to get under control," Feoktistov stated at the summit in Washington on Thursday.
The foreign ministry official made the comments at the 17th regular session of the Inter-American Committee Against Terrorism (CICTE).
Feoktistov noted that drugs production in Afghanistan saw an uptick in 2016, with its end value reaching some $110 billion.
On March 8, a US defense official said oil and gas extraction remains the main source of revenue for Daesh. The official has also explained that the Islamic State is still able to finance its operations since it has significant cash reserves seized on controlled territories.
