Three Ontario men charged in an alleged terrorist plot will make another court appearance later this month, following a brief hearing on Wednesday.

Khurram Syed Sher, 28, of London, Ont., Hiva Mohammad Alizadeh, 30, and Misbahuddin Ahmed, 26, both of Ottawa, were arrested and charged last week in an alleged terrorist scheme that police say reaches from Canada to Afghanistan, Iran and Pakistan.

Sher and Ahmed have been charged with conspiracy to facilitate terrorist activity.

Alizadeh has been charged with conspiracy, committing an act for terrorism purposes and providing or making available property for terrorism purposes.

On Wednesday, the three men appeared in an Ottawa courtroom through a video link. The trio has so far been denied bail.

Sher will get his next court date on Friday, while Ahmed will appear in court on Sept. 15. Meanwhile, Alizadeh will have his next appearance in court on Sept. 16.

All three men are Canadian citizens.

The men were arrested following a year-long investigation and police allege that 50 circuit boards seized were designed to remotely detonate bombs.
