A Quebec woman already accused of supplying weapons parts to Lebanon is now facing a serious terrorism charge.
The RCMP said Friday the charge followed an investigation that alleges Mouna Diab committed offences for the benefit of a contact linked to Hezbollah.
Hezbollah has been considered a terrorist organization by Canada since December, 2002.
Ms. Diab appeared briefly in court to be formally charged, the federal police force said.
Ms. Diab, 26, was arrested in May, 2011 at Montreal's Trudeau International Airport for allegedly trying to smuggle parts for an AR-15 rifle in her luggage.
She was charged last October with illegally exporting weapons to Lebanon. A United Nations resolution prohibits Canadians from selling arms to anyone in Lebanon.
That charge, under the UN resolution, carries a maximum 10-year sentence.
A deeper investigation by the Integrated National Security Enforcement Team's Quebec branch brought about an alleged connection to Hezbollah and a new charge: committing an offence for a terrorist group, a charge that carries a maximum sentence of life in prison.
"It is alleged that Diab was acting under the direction of a contact person in Lebanon who is associated with Hezbollah," the RCMP said in a statement.
The RCMP alleges Ms. Diab was shipping parts through other Lebanese community members, although those people were unaware of what they were carrying.
The RCMP issued a warning Friday for travellers to be aware they can face charges if they are caught with illegal items. The force cautioned people not to carry packages on behalf of a third party if the contents are unknown.
