Celtic have been fined by UEFA after their supporters set off fireworks in a Champions League qualifier against Cliftonville.
The Hoops will have to pay 5,000 euros (£4,200) after being found guilty of breaching article 16.2 of the governing body's regulations.
The incident took place in the second qualifying round second leg at Celtic Park on July 23.
Neil Lennon's men defeated the Northern Ireland champions and also overcame Elfsborg and Shakhter Karagandy to book their place in the group stages.
A statement on UEFA's website confirmed: "Celtic FC have been fined E5,000 after a charge of improper conduct of supporters (setting off of fireworks) in their second qualifying match at home to Cliftonville FC on 23 July 2013."
Celtic were fined 25,000 euros (£21,000) for fans' misbehaviour in the Europa League game against Udinese in Italy in December 2011.
After the 1-1 draw at the Stadio Friuli, the Parkhead club were charged with "the displaying of a banner of an offensive nature and the setting off of fireworks by supporters".
