 During the second half of April and all of May, pro-LNA air force conducted multiple air strikes against pro-GNA forces across western Libya, but most of the air strikes were conducted on pro-GNA positions in and around the city of Tripoli, with pro-GNA air forces responding in kind by launching multiple airstrikes against pro-LNA positions around the city of Tripoli—several airstrikes were also allegedly conducted against pro-GNA positions in Tripoli by UAE air force Wing Loong 2 UAVs, which is supported by the findings of the remains of Chinese-made LJ-7 guided missiles on the sites of those air strikes.On May 12, it was confirmed by russian journalists that pro-LNA air forces have during their western Libya offensive extensively used an Il-18D transport aircraft, serial ER-ICS, which is being flown by an unknown foreign company from Kazakhstan (it previously belonged to Moldovan Sky Prim'Air company, and was used by pro-LNA air forces as transport since 2015), for an aerial supply bridge, to regularly transport ammunition from Benina air force base to Gharyan.On 13 June 2019, pro-LNA forces claimed that they shot down a pro-GNA L-39ZO Albatros fighter jet in Dafniya, south of Misrata, as it was bombing pro-LNA positions around the town, however because Dafniya is over 100 kilometers away from the nearest pro-LNA frontline positions, this is highly questionable claim (pro-GNA forces confirmed that they lost the plane, but deny the pro-LNA claim of shooting it down, claiming instead that their L-39ZO fighter jet crashed due to technical malfunction after taking off); the pilot failed to eject, and was killed as a result.
