Sir: Since the start of fighting nearly two weeks ago, 572 Palestinians have been killed and nearly 3,000 wounded, according to Gaza Health Ministry official Ashraf al Kidra. The indiscriminate use of missiles, bombs and chemical weapons against innocent unarmed Palestinian civilians is deplorable to say the least. But more than that the criminal silence of the European Union, United States, United Kingdom, Organization of Islamic Countries, Arab League and other so-called civilized countries and champions of human rights is painful.
