A Canadian academic was charged on Saturday over the deadly 1980 bombing of a Paris synagogue after losing his six-year legal battle against extradition over the notorious attack.

Hassan Diab, a Canadian of Lebanese descent, appeared before an anti-terror judge just hours after arriving in Paris from Montreal.

The U.S. House of Representatives on Friday approved construction of the controversial Keystone XL pipeline to bring oil from Canada, but the measure could still find itself blocked in the Senate.

The project, which would bring oil from tar sands in Alberta province to US refineries, passed the Republican-controlled House by 252 votes to 161, with 31 Democrats supporting the measure.

Canada's top court refused Thursday to hear a university professor's final plea to halt his extradition to France, effectively ensuring he will face trial for the 1980 bombing of a Paris synagogue.

The decision brings to an end 60-year-old Hassan Diab's six-year legal battle to avoid what he said would be an unfair prosecution in France for a crime he insists he did not commit.

Canada on Monday ramped up travel restrictions for people returning from Ebola-stricken countries, officials said, and said "high risk" travelers should be closely monitored for symptoms or admitted to a special facility.

People returning from Liberia, Guinea or Sierra Leone who have come into contact with the virus are told to report to local health officials and self-monitor for up to 21 days, Canada's Public Health Agency said.

Canada's Immigration Minister Chris Alexander Wednesday unveiled plans to ban entry to migrants who practice polygamy and what he termed "barbaric cultural practices."

The move follows a spate of so-called "honor" killings over the past decade involving immigrant families from the Middle East and South Asia.

Canada suspended development assistance to Burkina Faso on Tuesday after the West African country's military seized power in one of the world's poorest nations.

"Given the current climate, it is not possible to provide development assistance dollars directly to the government of Burkina Faso and ensure they are spent effectively and as intended," International Development Minister Minister Christian Paradis said in a statement.

Visiting French President Francois Hollande brought a message of solidarity in the global fight against terrorism to Canada's parliament Monday, less than two weeks after a lone gunman stormed its halls.

"In the face of terrorism, there is no room for backing down, for concession, for weakness, because terrorism threatens the values on which both of our countries are based," Hollande said in a speech to Canadian lawmakers.

President Francois Hollande began the first visit to Canada by a French leader in a quarter of a century on Sunday, flying in to the country's oil-rich west to drum up trans-Atlantic trade.

A new trade pact between Canada and the European Union is due to come into effect in coming years, eliminating 98 percent of tariffs on goods and services and potentially boosting commerce by a fifth.

Canada conducted airstrikes on Islamic State positions in Iraq for the first time on Sunday, while reports emerged that the jihadist group had executed more than 200 tribespeople in recent days.

"Today's strike demonstrates our government's firm resolve to tackle the threat of terrorism and to stand with our allies against ISIL's atrocities against innocent women, children and men," Canadian Defense Minister Rob Nicholson said in a statement.

Canada's Conservative government said it is suspending visa applications for residents and nationals of countries with "widespread and persistent-intense transmission" of the Ebola virus.

With Friday's decision, Canada joined Australia in suspending entry visas for people from Ebola-stricken countries in West Africa in an attempt to keep the deadly disease away.
