A last minute winner sent Hibernians top of the GoHealth Premiership.
Birkirkara slightly against the run of play took the lead mid-way through the first half when Kemar Reid’s shot on the run left Haber stranded.
The equaliser for Hibs came in the 69th minute when Joao Teixeira headed home from close range.
It looked like the game was heading for a draw until, in the sixth minute of extra time, Cleiton won the race for a long ball forward and fired low past Martinez to clinch the win for Hibernians.
