Letters: Syria's civil war is an affront to humanity
* This year is the 100th anniversary of World War I and it is natural that there will be debates and arguments on the reasons for a war that led to the deaths of an estimated 10 million soldiers.
But modern war 100 years later is equally inhumane, with a civil war on an epic and vicious scale affecting civilians in Syria. Efforts by the UN and the US, urging both sides to end the conflict, have failed.
The war is three years old and last year the UN Secretary General said 100,000 people had been killed and 9.5 million had fled their homes within Syria. This is twice Ireland's population.
