A second pro-LNA MiG-23ML fighter jet, serial number "6132", was shot down on 8 February 2016 by the Islamists during its bombing raid on Islamist positions in the town of Derna (LNA claims it crashed due to technical problems), its pilot colonel Younes al-Dinali ejected safely. A third pro-LNA fighter jet, this time an MiG-23UB serial number "7834", was shot down by the Islamists during its bombing raid on Islamist positions in Garyunes area, Benghazi (LNA claims that it crashed due to technical problems), on 12 February 2016, its pilot ejected safely. In response to such heavy losses, during March and April 2016, two MiG23BN fighter jets with in-flight refueling probes, serial numbers "8985" and "4136", which were in storage ever since the early 1990s at Al Abraq air force base, were quickly brought back to service by pro-LNA air force engineers and technicians. But despite that, heavy losses of pro-LNA air force continued.
