The recently imposed sanctions on Iran by the UN Security Council are yet another evidence of the double standards in international relations. On one hand, the Israeli bloodbath against unarmed civilians and peace activists on board the freedom flotilla has gone unnoticed, without any punitive action by the UN. But the UN has chosen to classify the 'grave threat posed by the Iranian nuclear programme as worthy of sanctions. We will ensure that these sanctions are vigorously enforced, just as we continue to refine and enforce our own sanctions on Iran said US President Barack Obama. And, then, they cannot comprehend the reasons of hatred against the US among Muslims? -MOIN AHMAD, Bahawalpur, June 10.
