The attacks on Paris and Lebanon show, once again, the cold-blooded and shameless nature of members of the group known as Islamic State (IS).
They kill innocent people and, in the areas of Iraq and Syria they have occupied, they force many women into sexual slavery.
It is clear that governments from different countries have to do more than the air strikes on IS-controlled territories.
While air strikes might make some impact in the short term, the leaders of countries such as the US and France must work together to come up with a long-term solution.
We need to try and ask why IS exists in the first place. The group seems to thrive on sectarian strife.
There are still people with set beliefs who refuse to practise religious tolerance and respect religions other than their own. Some of them move towards extremism, preach hate and join groups like IS. Governments need to try and deal with religious intolerance within their own borders.
