Newcastle United were denied a famous win in Paris Saint-Germain via a late Kylian Mbappe penalty.
Alexander Isak's first half goal looked to be the difference between the two sides until Mbappe converted from the spot in the eighth minute of stoppage time.
The spot-kick was awarded in controversial fashion after the ball hit the chest of Tino Livramento before striking his arm.
Eddie Howe's side, without 14 senior players either through injury, suspension or ineligibility, were unchanged from Saturday's 4-1 win over Chelsea.
After riding out the early PSG onslaught, the Magpies took the lead in the 24th minute when Miguel Almiron's shot was parried by Gianluigi Donnarumma and into the path of Isak, who tapped home from close range.
The Sweden international became the first Newcastle player to score an away goal in the Champions League since Alan Shearer two decades ago.
The hosts piled on the pressure in the second half and after missed chance after missed chance, it felt as though it was to be Newcastle's night until the referee pointed to the spot in the closing minutes.
Here's our Newcastle United player ratings from a memorable night in the French capital:

10. Miguel Almiron - 8
A sensational first half display by the Paraguayan. Clever, brave, and carried the ball superbly. Faded after the break but his work rate never stopped. | AFP via Getty Images
11. Anthony Gordon - 7
His usual quality wasn’t there and he gave the ball away on a few occasions but ran himself into the ground down the left. Defensively very good in the second half. | AFP via Getty Images
12. Alexander Isak - 7
Missed a sitter 12 minutes in but made up for it by netting the opener. Was a bit of spectator in the second half with Newcastle pegged in. | AFP via Getty Images
