PEACE campaigners called for a huge mobilisation for the pro-Palestinian march through central London tomorrow.The call follows the announcement by the Israeli today that the ceasefire agreement with Hamas had come into effect and that troops were withdrawing to agreed-upon deployment lines.Even so, explosions and smoke were seen in Gaza today, with attacks taking place hours after Israel’s Cabinet-approved President Donald Trump’s plan for a ceasefire in the Gaza Strip, the release of the remaining hostages and of Palestinian prisoners.
