Sajjan said Friday that the three-month extension will enable the government to assess the evolving nature of the fight and Canada's contributions as a coalition partner.
Colonel Joe Scrocca, a spokesman for the Baghdad-based coalition, said: What you see now is not the use of civilians as human shields.
ISIS is smuggling civilians so we won't see them and trying to bait the coalition to attack to take advantage of the public outcry and the terror.
A statement issued by Abadi's press office on Thursday said that the Iraqi premier received a phone call from Trump during which they discussed the consolidation of ties between the two countries in all fields, the victories achieved against ISIS, and the global support to Iraq in the fight against terrorism.
Votel also told the committee that almost 800 Iraqi security forces have been killed and 4,600 wounded in the increasingly brutal battle to retake Mosul from IS extremists that began last fall.
One probe seeks to establish whether a Belgian F-16 was involved in the March 17 strike which killed over 200 people.
The UNAMI statement came as the Iraqi security forces backed by anti-IS worldwide coalition are carrying out a major offensive to drive out the IS militants from its last major stronghold in the city of Mosul in northern Iraq.
"It is very hard to mitigate" the risk of civilian casualties when we have to address "an immediate threat coming from a building", the source said.
Scrocca said officials had suspicions of the tactic, and yesterday's video now provides proof and offers signs of what to look for.
Once a coalition commander approves a strike, Iraqi officials must sign off. In the first 37 days of the Iraqi offensive to take western Mosul, 284 Iraqi troops were killed and more than 1,600 were wounded.
Abadi, for his part, said Iraqi forces were doing their "utmost" to protect civilians and lashed out at the terrorists for intentionally putting civilians at risk while also "intensifying their propaganda machine to spread rumors".
