Omnipol acts as the intermediary in government-to-government sales of defence equipment , meeting the needs of air and ground forces in more than 60 countries . From 1975-1981 , roughly 700 tons of Semtex plastic explosive were purchased and exported to Libya by Omnipol . As such , implications have been drawn that Semtex usage on the part of militant factions , such as the Irish Republican Army and the Palestine Liberation Organization , may have been originally sourced from Omnipol , given Libyan ties to such groups . Notably , it has been alleged that the Semtex utilized to carry out the 1988 bombing of Pan Am Flight 103 over Lockerbie , Scotland was in fact indirectly sourced from Omnipol via Libya , which , though not entirely substantiated or corroborated , fits in with verifiable records of Omnipol 's arms sale connections to Libya
