Mbokani was caught up in the 2016 Brussels bombings, alongside his international teammate Cédric Bakambu. Though both escaped unscathed, Mbokani was reportedly left "shaken". In the aftermath of this, after being sanctioned for missing a game as a result, he retired from international football with 31 caps. However, he returned to DR Congo's squad for the 2017 Cup of Nations in Gabon, and he was recalled to the national team in March 2019, although he withdrew due to injury.
