CAIRO (Reuters) -Organisers of a march to the Egyptian border with Gaza said on Tuesday that three participants were abducted by plainclothes officers in Cairo amid a wave of arbitrary detentions, deportations and abuse by security forces.

The Global March to Gaza is a civilian-led initiative to march from Arish, Egypt, to the Rafah border crossing with the Gaza Strip beginning on Sunday. Once in Rafah, the goal was to set up a camp and work to break the Israeli blockade of Gaza, provide humanitarian aid to the strip and protest against Israel's actions in the territory.

More than 40 Canadians who were taking part in a global march to Gaza have been detained in Egypt and blocked from reaching the border of the war-torn enclave.
