A Quebec man has been arrested in connection with an online threat to attack Austria and Germany, the RCMP said Thursday.

Said Namouh, 35, was taken into custody on Wednesday in Maskinonge, Que., northeast of Montreal, said police.

The alleged bomb plot did not involve any Canadian targets, an RCMP spokesperson said.

"We want to reassure people that the investigation being carried out has never found a direct threat to Canada," Cpl. Elaine Lavergne said.

Namouh is scheduled to appear in court on Friday in Montreal.

Also on Wednesday, Austrian officials announced they had arrested two men and a woman in connection with the online video threat.

In the statement — posted online in March — suspected Islamic militants threatened to attack Germany and Austria unless the two countries pulled their troops out of Afghanistan.

Liberal Senator Colin Kenny, chairman of the Senate standing committee on national security and defence, said the arrest was a product of a lengthy joint investigation by the RCMP and their Austrian counterparts.

"They've been working in a co-operative way with the Austrians for some time on this," he said.

Police believe suspects have al-Qaeda ties

Public Safety Minister Stockwell Day congratulated police and security authorities both in Canada and abroad for their work.

"It's disturbing that this type of thing could have been going on with a Canadian component," he said Thursday. "But it's encouraging that the alleged attempts at some type of terrorist event appear to have been averted."

Austrian Interior Minister Guenther Platter said the suspects arrested in Austria were believed to have contact with al-Qaeda and that one of the men was suspected of being the creator of the video. The other man was suspected of contributing to the video, he told reporters.

All the Austrian suspects lived in Vienna and were arrested following a bugging operation, said Erik Buxbaum, Austria's general manager for public security. The three are all in their 20s and unemployed, he said.
