The refusal to transmit the Disasters Emergency Committee appeal has left it isolated and exposed. Its senior journalists feel betrayed, but dare not speak out because of their terms of service. Its old soldiers like myself cannot believe what we are seeing – or, in the case of the DEC appeal, not seeing. The argument that it should not be shown because the humanitarian disaster in Gaza was man-made does not stand up to a moment's scrutiny. The sufferings of the people of Darfur and the Democratic Republic of Congo were also the result of man's inhumanity to man. But those appeals were shown without objection. The BBC's management acts as if there is one rule for Africans and another for Palestinians.
