Gaza rally commemorating Israel pullout marred by deadly explosion

At least five Palestinians were killed and 25 others injured in an explosion near the separation fence along the Israeli frontier with Gaza during a demonstration marking the anniversary of Israel's withdrawal from the Gaza Strip in 2005. The cause of the blast is unknown, with witnesses claiming Israeli soldiers fired tear gas before the explosion. The Israeli army denied involvement, stating that demonstrators were attempting to throw a bomb over the fence when it detonated. The enclave of Gaza, home to two million people, remains under Israeli blockade, with strict control over movement and goods.
