The federal government has not yet received a report on the 鈥渇riendly fire鈥 death of a Canadian soldier killed in Iraq two months ago, according to Immigration Minister Chris Alexander.

Alexander told CTV's Question Period that the government has not seen the report on Sgt. Andrew Doiron's death in Iraq in March.

"We have to let those conducting them (the investigations) tell us when they're finished, tell us when they've come to a conclusion. That hasn鈥檛 happened yet. The report hasn't been received," said Alexander.

Doiron was accidentally gunned down by Kurdish forces in a friendly fire incident on March 6, near an observation post along the front lines in northern Iraq.

Sources told 麻豆影视 that Canadian special forces pulled back from the front lines after Doiron's death, and that they will be moved back to the front lines after the report on the incident.

Speaking in Kuwait Sunday, Chief of the Defence Staff Tom Lawson indicated that . Lawson also hinted that the investigations into Doiron's death have found Canadian soldiers blameless.

"I think we'll see the fatigue of the soldiers who were at the front, the peshmerga at the front, would have played a part," said Lawson.

Prime Minister Stephen Harper made a surprise visit to Iraq on Saturday, where he met with the country鈥檚 prime minister and announced $139 million for Iraq, Syria, Jordan and Lebanon to help the region deal with the overwhelming refugee crisis triggered by the rise of the Islamic State (ISIS). He then made his way to Kuwait for an overnight visit with the Canadian Air Force personnel conducting air strikes on ISIS in Iraq and Syria.

Canada has 69 special forces training Kurdish peshmerga fighters in northern Iraq. It has also contributed six CF-18 jetfighters, a CP-140 Aurora surveillance plane and a C-150 Polaris tanker to the U.S.-led air campaign bombing ISIS strongholds. The Canadian mission was recently extended to the end of March 2016.

Last week, the New York Times reported that the U.S.-led coalition, which includes Canada, is considering whether it needs to broaden its campaign against ISIS to countries like Libya.

Alexander said Canada is focused on its role in Iraq and Syria.

"We're concerned about the situation in Libya but right now our military mission is in Iraq. The air missions have been expanded to Syria because that's where ISIS is based," said Alexander.

Harper's trip to Iraq comes six months ahead of October's scheduled federal election. Canada鈥檚 involvement in the fight against ISIS will likely be a wedge issue between the federal parties in the lead-up to and during the election.

The prime minister was travelling this weekend with one photographer and two videographers, who caught his every move on camera. The Conservatives will likely use the footage as election material. Alexander rejected criticism that the trip was just an election photo-op.

"I think anyone who argues that international terrorism has somehow been invented by any western leader, any external leader, for their purposes is taking a very cynical view. These networks are real," said Alexander.

Canadian response to Nepal earthquake

On Saturday, the government announced that Canada will send a disaster assessment team to earthquake-stricken Nepal and provide an additional $5 million for relief efforts. Alexander said that money will funneled through "proven channels," including Canadian NGOs operating in the region, to provide food, shelter and coordination for searches in remote areas.

One thing the government is not considering, however, is sending helicopters to Nepal, said Alexander. Other countries have sent helicopters to the region to help with search and rescue efforts in remote areas.

Critics have said the government was too slow in responding to concerns about missing Canadians in remote regions. But Alexander stood by the government's handling of the situation Sunday.

"I think it's been an excellent response by Canada in a circumstance where we didn鈥檛 have an embassy on the ground, a high commission on the ground, as we do in most of the countries of the world."

Some Canadians in Nepal during the earthquake were transported by a Canadian military plane to Delhi last week.
