French minister says government has dismantled 15 terrorist networks in wide-ranging campaign

France's justice minister says the government has dismantled about 15 terrorist networks as part of its wide-ranging campaign to eradicate terrorism within the country's borders.

Christiane Taubira told an open meeting of the U.N. Security Council's Counter-Terrorism Committee on Tuesday that following last month's attacks on the Charlie Hebdo weekly newspaper and a kosher supermarket that killed 17 people, along with the three gunmen, that international action is essential to combat the increase in terrorist attacks.

She said France is looking at the sophisticated propaganda, indoctrination and methods used to recruit terrorists, including social media and video games.

France is also reinforcing measures to fight against racism and xenophobia, to protect victims and witnesses, and to help people who agree to become informers, Taubira said.
