Ukraine demands return of bodies; Canada calls for full responsibility

Iran said on Saturday its military had shot down a Ukrainian plane killing all 176 aboard in a "disastrous mistake", saying air defenses were fired in error while on alert after Iranian missile strikes on US targets in Iraq.

Iran had previously denied that it had downed the plane. Following are some reactions to Tehran's announcement:

Ukrainian President Volodymyr Zelenskiy

"I insist on immediately completing the identification of the bodies and their return to Ukraine," he wrote on Twitter after speaking to Iranian President Hassan Rouhani. "The perpetrators must be held accountable."

In a televised address later, he said the findings by Ukrainian experts in Iran meant that the truth about the crash could not be concealed.

Canadian Prime Minister Justin Trudeau

"What Iran has admitted to is very serious. Shooting down a civilian aircraft is horrific. Iran must take full responsibility," Trudeau told a news conference.

"Canada will not rest until we get the accountability, justice, and closure that the families deserve."

British Prime Minister Boris Johnson

"Iran's admission that Ukraine International Airlines Flight 752 was shot down by mistake by its own armed forces is an important first step," Johnson said in a statement.

"We now need a comprehensive, transparent and independent international investigation and the repatriation of those who died ...We can all see very clearly that further conflict will only lead to more loss and tragedy. It is vital that all leaders now pursue a diplomatic way forward."

"Ultimately, Iran made an awful mistake," said the official, who spoke on condition of anonymity. "Iran's reckless actions have again had devastating consequences."

"There's nothing you can do to cover it up or hide it ... Evidence is evidence."
