Oumar Diakite, the match-winner against Mali, was sent off while celebrating his goal and was suspended here along with captain Serge Aurier, Odilon Kossounou and Christian Kouame.
Among those coming in were Brighton winger Simon Adingra, who got the equaliser against Mali, and Haller, the talismanic forward who was finally fully fit.
DR Congo were looking to avenge their 3-1 defeat by the Ivorians in their last appearance in the AFCON semi-finals, in 2015.
– Congo protest –
Their players have been spurred on during this tournament by a determination to raise awareness of the plight of millions of Congolese affected by ongoing violence in the east of the country.
The Congo team used the national anthem to protest, each covering their mouth with one hand and using the other to imitate a gun pointing at their heads.
Apparently unperturbed by the hostile home crowd, the Leopards started well and had the ball in the net in the ninth minute.
Cedric Bakambu knocked the ball out of goalkeeper Yahia Fofana’s grasp and in at a corner, but the goal was disallowed by the Libyan referee for a foul.
The biggest chances of the first half fell to the Ivorians, who grew as a threat as the interval approached.
Haller rose unmarked in the box only to somehow head wide from Wilfried Singo’s inviting cross in the 40th minute. Moments later, Franck Kessie crashed a shot off the post.
Kessie threatened again just before the hour mark with a powerful strike that forced goalkeeper Lionel Mpasi into action, but the breakthrough followed soon after.
Max-Alain Gradel held up a cross into the box from the right and Haller swung his leg in hope rather than expectation. The connection was not great but the ball bounced down into the ground and then looped over the head of the helpless Mpasi and into the net.
Frenzied celebrations ensued, while Fae leapt around in his technical area.
The hosts then went for the kill, with Haller heading onto the roof of the net from an Adingra corner and sending a lob wide when left with just Mpasi to beat.
One goal was enough and a deafening roar greeted the final whistle.
