A Canadian "dual national" living in Lebanon is believed to be involved in the deadly bus bombing in Bulgaria last July, Foreign Affairs Minister John Baird confirmed Tuesday.
The individual had dual Canadian and Lebanon citizenship, but lived in Lebanon, said Baird, adding that the suspect is still at large, and it remains unclear when he was last in Canada.
"This is not a resident of Canada. It's a dual national who I am told resides in Lebanon," Baird told a news conference on Parliament Hill.
"I couldn't even tell you the last time this person was in Canada."
Bulgaria's interior minister says the suspect, who entered the country with a Canadian passport, is believed linked to Hezbollah, the Shiite militant group and political party that Canada has designated a terrorist organization.
"We have followed their entire activities in Australia and Canada so we have information about financing and their membership in Hezbollah," said Bulgarian Interior Minister Tsvetan Tsvetanov.
The attack killed five Israelis and their Bulgarian driver.
It's the second time in recent weeks that a foreign government has alleged Canadians took part in terrorist attacks abroad.
Ottawa has yet to corroborate a claim by Algeria that at least one Canadian was among terrorists who staged a deadly attack on a Saharan gas plant last month.
Baird - who noted that Canada has been working alongside the Bulgarian government in recent weeks - said the co-operation from Bulgarian authorities has been markedly better than that from Algeria.
"We've had a more robust engagement with Bulgaria, and they provided more information," he said. "The situation in Algeria is just completely different. We don't even have a name, which is obviously of concern."
