Britain and Russia plan to jointly introduce a Security Council resolution today urging countries to ban the incitement of terrorist acts, and they hope world leaders will adopt the high-profile measure during a U.N. summit in September.

Supporters say the measure could help stem hate speech and rein in inflammatory media, and would address international terrorism while a more comprehensive global treaty on the matter languishes at the U.N.

Inevitably, 'human rights groups' (who can sometimes seem more concerned about the rights of terrorists than their victims) are concerned that this could restrict free speech and the right to political asylum.

The resolution also calls on all countries to deny safe haven to those who engage in incitement. Although previous counterterrorism resolutions have created committees to monitor terrorist networks, freeze their financing and remove their protection, the new measure attempts to stop the seeds of hate from germinating, its sponsors say.

"When someone gives the floor to terrorists, he must also be responsible for the possible fallout, because it is not just someone's view, but a chance for a terrorist to use the podium to propagate violence," said Russian Ambassador Andrey Denisov. "Terrorism must not be seen as just a political act, but as a social and political phenomenon which must be addressed. It is a broader way to look at terrorism and combat it."
