US has been deeply engaged with France: John Kerry

Asserting that Washington's relationship with Paris is constant and is based on shared values, United States Secretary of State John Kerry on Monday said his country has been deeply coordinating with France from the moment the horrific attacks took place in that nation.

"I want to emphasize that the relationship with France is not about one day or one particular moment, it's an ongoing long-time relationship that is deeply deeply based on the shared values and particularly the commitment that we share of the freedom of expression," Kerry told the media here.

"The President and our administration have been coordinating very very closely with the French on intel, law enforcement across the board and we will continue to make available any assistance that may be necessary," he added.

Millions of people across France held rallies in Paris and other cities following the deadly attack on the satirical magazine Charlie Hebdo's headquarters last week.

The rallies also took place in London, Washington, Montreal and Berlin where thousands of people gathered.

Last week, two terror attacks in Paris shook the world. The first, an attack on French satire magazine Charlie Hebdo's offices on Wednesday, left 12 people dead, including two police officers, with a further five wounded. The second attack was a gunman taking several people hostage at a kosher supermarket on Friday, leaving four people dead.
