Thirty fugitives wanted for war crimes or crimes against humanity are believed to be hiding in Canada, Prime Minister Stephen Harper's government has said.

The country's Border Services Agency website named the suspects, appealing for the public's help to find them.

The fugitives are listed as having come from regions including the Middle East, Africa and Latin America.

Public Safety Minister Vic Toews said the suspects should be tracked down and removed from Canada.

The website said the wanted men came from Afghanistan, Algeria, Angola, El Salvador, Ghana, Guatemala, Haiti, Honduras, Iraq, Nigeria, Pakistan, Peru, the Democratic Republic of Congo, Somalia, Sri Lanka, Sudan and the former Yugoslavia.

The Border Services Agency did not indicate any specific charges against the suspects, but asked anyone with information about them to call a hotline.

On Wednesday, Immigration Minister Jason Kenney said Canada planned to revoke the citizenship of 1,800 people suspected of obtaining their status fraudulently.
