French authorities have stepped up the security at the train station, shopping malls and tourist sites, as the intelligence reports warn about threat by Islamic radical group. Last week, thousands of people were evacuated from the Eiffel Tower.

It was in reaction to the specific intelligence information regarding the bomb threat. In the northern desert region of Niger, two African and five French people who were working for French owned nuclear-reactor company Areva, were kidnapped by the armed men.

After French forces killed many terrorists in an aborted attempt to rescue a French hostage, at one of its bases in Northern Mali, the radical unit had issued threats to France. The hostage was subsequently killed by the terrorists. France is on alert since the govt. passed Ban Burkha bill.

In response, an Islamic radical group had again threatened to blow up the public transit system.

Mr. Dalil Boubakeur, the rector of the biggest Mosque in Paris, has been provided with the armed security, as a sign of taking terrorist threat seriously. The French authorities have recalled the terrorist attacks of 1995 and 1996 and are responding with the preventive action.
