Finally, 24 days into the offensive on Gaza that already cost the lives of 1300 Palestinians, Ban Ki-moon demanded "accountability and justice". Denouncing the latest Israeli bombing on a UN school where Palestinian civilians had taken shelter, Ban condemned the attack as "outrageous and unjustifiable".

Pierre Krähenbühl, commissioner-general of the UNRWA also said: "Last night, children were killed as they slept next to their parents on the floor of a classroom in a UN-designated shelter in Gaza. Children killed in their sleep; this is an affront to all of us, a source of universal shame. Today the world stands disgraced."

The disgrace is that such a 'serious violation of international law', as Krähenbühl admit it, is the latest in a long list of such violations and a history of indiscriminate killings of civilians in Palestine (not to forget Lebanon) by Israeli forces, which always fail to be 'serious' enough to call for international sanctions against Israel.

The world might stand today, as yesterday and perhaps tomorrow, in momentary disgrace yet remain amnesiac to a history of military occupation and repeated violence incurred by the State of Israel. Momentous moral outrage should materialize in a long-standing political act of 'accountability and justice'. Otherwise lives of Palestinians will continue to be crushed with impunity by Israeli forces and regarded as disposable by its apologists. And the world will remain complicit.

Signs of Conflict posts here three solidarity posters dating as far back as the late sixties, which bare witness to the history of violence on Gaza at least since its military occupation in 1967. The first two are drawn from the collection of A. Bou Jaoudeh, one is designed by the late Palestinian activist and novelist Ghassan Kanafani in 1970, and the third is a new powerful illustration by Jana Traboulsi denouncing the more recent chain of assaults since 2004.

1- Solidarity with Gaza. Anonymous artist, c. late 1960s. (from the collection of A. Bou Jaoudeh)

2 - Ghassan Kanafani. "Support the heroic struggle of the Palestinian people in Gaza against Israeli repression". PFLP 1970. (from the collection of A. Bou Jaoudeh)
