The International Monetary Fund (IMF) has questioned the rationale and procedure that led to Mali buying a £24 million presidential jet, given the country's pledges to fight poverty, a spokesman said.
The IMF has contacted Malian authorities about the plane purchase as well as a separate £124 million state guarantee loan secured by a private company with a Malian bank, to provide supplies for the army, the spokesman said.
The IMF spokesman added that the process of getting this information will delay the first review of its post-war aid package and, as a result, monetary disbursements will be delayed.
Two journalists from France kidnapped and killed in northern Mali were shot, French authorities say.
Ghislaine Dupont, 51, and Claude Verlon, 58, were abducted on Saturday after interviewing a rebel leader in Kidal.
French Foreign Minister Laurent Fabius said the two were shot multiple times and their bodies were found near the vehicle that whisked them away.
But Mr Fabius failed to clarify who was behind the killings and why the pair was targeted.
Two French journalists killed in northern Mali on Saturday were "coldly assassinated", France's foreign minister Laurent Fabius has said.
He added that "terrorists" were behind the "heinous and revolting" attack and security in the Kidal region of the west African country would be increased.
Speaking after a special cabinet meeting to discuss the deaths, Mr Fabius said: "Security in the area and the surrounding areas, especially for French nationals, will be increased".
France's army never had any visual or physical contact with the gunmen who killed two French journalists in northern Mali on Saturday, an army official said.
Armed Forces spokesman Colonel Gilles Jarron said the bodies of the two reporters had been found by a French patrol some 10 kms (6 miles) to the east of Kidal after they were tipped off by a local resident that the journalists had been taken.
Two French helicopters arrived on the scene 50 minutes after the patrol found their bodies, he said. Earlier, several French media reports said a French helicopter had tracked the kidnappers's vehicles after the abduction.
The deaths come four days after France rejoiced at the release of four French citizens held for three years by al Qaida's affiliate in North Africa.
France's foreign ministry has confirmed two French journalists were killed in the north Malian town of Kidal after being taken by armed gunmen.
"Claude Verlon and Ghislaine Dupont, journalists at RFI, were found dead in Mali," the ministry said in a statement. "They had been kidnapped by armed gunmen in Kidal."

Thousands of refugees from northern Mali have fled their homes into a desert camp in neighbouring Mauritania where conditions are dire.Read the full story ›
Malian refugees in Mauritania are enduring "deplorable" conditions in the Mbera refugee camp that is causing levels of malnutrition to increase, according to MSF.
The situation in the camp has worsened since the Frence led military intervention in January, according to the medical aid agency.
Conditions at the camp are so bad that many healthy children are getting ill upon arrival and malnutrition rates have more than doubled. MSF said:
"The number of children admitted per week for severe malnutrition has more than doubled, [...] despite the nutritional status of the new refugees being generally good when assessed on arrival in the camp."
The MSF report, Stranded in the Desert, is based on testimony from more than 100 residents of the Mbera camp, near the border with Mali.
Thousands of refugees fleeing the ongoing conflict in Mali are facing appalling living conditions in the Mbera refugee camp in Mauritania, according to medical aid agency Medecines Sans Frontieres (MSF)
The camp, located in a remote, arid region close to the border with Mali is home to 70,000 people who are relying entirely on aid agencies to meet their most basic needs.
Provisions are "far from adequate" with a desperate shortage of toilets and supplies: In January when MSF arrived there were only four latrines for 12,200 people.
The area suffers from a chronic lack of water and refugees are receiving only 11 litre of water a day in 50C heat - 9 litres less than recommended.
Malian officials have been forced to replace the gift of a camel to French President Francois Hollande for his help in confronting Islamist rebels after the first one was eaten.
Mr Hollande was awarded a camel during a visit to the former French colony in February, joking that he would use it back in Paris to escape congestion.
But he apparently learned from his defence minister that the family left to tend his animal in Timbuktu had, in fact, consumed it.
Embarrassed Malian officials quickly pledged to send "a bigger and better-looking camel" to the French capital.
"We are ashamed of what happened to the (first) camel," an official said. "It was a present that did not deserve this fate."
