Turks and Kurds may be trading accusations over responsibility for the execution-style murder of three Kurdish activists in the heart of Paris last week, but they agree on one point: the timing was no coincidence. The assassinations came just days after Turkey announced a new bid to find a political solution to its long-running conflict with its Kurdish population. The message? Peace-building will be no walk in the park. That’s because the conflict is too well-entrenched and the players too accustomed to violence — some 40,000 people have been killed in 30 years of insurgency and counterinsurgency. And also because it reaches into Iraq, Syria and Iran, not to mention Europe, where thousands of Kurds marched the streets last weekend to protest the killings.
