Jihadist supporters celebrate Paris terror attacks

Paris: Twitter accounts linked to jihadists are celebrating the attacks in Paris.

According to the SITE Intelligence Group tracking militant sites, Twitter posts attributed to jihadist supporters are speculating which group may be responsible. Many users expressed belief that the Islamic Group could be behind the carnage.

They used Arabic-language hashtags that translated to "Paris on fire" and "Caliphate state strikes France."

SITE says that accounts also circulated pictures of the attacks, and one pro-IS channel accused France of sending warplanes to bomb Syria and says "today it drinks from the same cup."

A French police official says top government officials including President Francois Hollande were headed to the Bataclan concert hall where hostages were taken.

Another official said at least 100 people died inside the hall. A police assault on the venue finished early Saturday, leaving at least two attackers dead, officials said.

The officials were not authorized to be named because operations were ongoing.

A French police official said at least 140 people have been killed inside a Paris concert hall where attackers seized hostages. The hostage-taking was one in a series of at least six attacks across the French capital.

Although no one has claimed responsibility for the Paris attacks, some terrorism experts say the Islamic State group is likely responsible.

Brian Michael Jenkins, a terrorism expert and senior adviser to the president of RAND Corp., said the extremist group is clearly the name at the top of everyone's list." He said this was because the tactic used - "multiple attackers in coordinated attacks at multiple locations" - echoed recommendations published in extremist group's online magazine,

James Woolsey, a former director of the CIA in 1993-195 and now chancellor at the Institute of World Politics, also told the BBC he suspected the Islamic State because the coordinated nature of the attacks required government-style planning.
