Gaza ceasefire petition

There is a petition at Avaaz to the UN Security Council, the European Union, the Arab League and the USA asking for a ceasefire in Gaza:

We urge you to act immediately to ensure a comprehensive ceasefire in the Gaza Strip, to protect civilians on all sides, and to address the growing humanitarian crisis. Only through robust international action and oversight can the bloodshed be stopped, the Gaza crossings safely re-opened and real progress made toward a wider peace in 2009.

They want 250 000 signatures. So far there are 52 254. You can sign the petition here.
