February 2012, the military of Honduras and Embraer began a study of the aging AT-27 cells for a possible reconditioning program. Later on that month, the Honduras defence minister disclosed that the reconditioning of six aircraft would cost US$10 million. In May of the same year, a Tucano intercepted an aircraft from which of cocaine were seized. In the following month, a Honduran Tucano shot down a drug-smuggling, twin-engined prop Cessna over the Bay Islands, killing the two occupants, including an undercover DEA agent. Honduran law does not permit shooting down illegal flights, so the event led to the dismissal of the Honduran general who ordered the attack. Iran Iran received 25 aircraft between 1989 and 1991. Between 2000 and 2001, the IRGC used Tucanos against Taliban positions and in drug-busting operations in the eastern Iranian borders. Iraq Iraq bought 80 aircraft produced under license by Helwan, with deliveries being completed in 1987. Following the end of the Gulf and Iraq wars, Iraq had no EMB-312 in its inventory. Mauritania In 2011, the Islamic Air Force of Mauritania received pilot training from the French Air Force and four ex-French EMB-312Fs, which still had two-thirds of their structural life, were delivered. The aircraft underwent a complete overhaul before being delivered, receiving wing hard points for gun pods and new radios. The type is based at Atar in the northwest of the country, where they are used in attack missions against Al-Qaeda Organization in the Islamic Maghreb (AQIM) guerrillas. In March 2012, Mauritanian EMB-312Fs intruded into Mali air space while attacking AQIM terrorist targets inside Mali; the two countries are cooperating in military action against these terrorists. Paraguay Paraguay received six aircraft in 1987. Six more were purchased in the late 1990s, but the deal fell through, and these machines ended up being the second batch sold to Angola. On 29 December 2010, three used ex-Brazilian aircraft were exchanged for four EMB-326GB (Xavante) trainer aircraft and one Boeing-707 transport aircraft. In 2011, the Paraguayan Tucanos with assistance from the Brazilian Air Force, went through a complete engine overhaul. The 3o Escuadrón de caza "Moros" in Asunción operates the Tucanos in counter-insurgency missions, forming the squads "Gamma" and "Omega" since 1996. In April 2011, Paraguayan Tucano fitted with 20 mm autocannon gun pods and ferry tanks were deployed at Mariscal Estigarribia Air Base to monitor illicit flights entering Paraguayan airspace from Bolivia.
