More than seven years after her son carried out an attack in Jerusalem, Azhar Abu Srour is still waiting to recover his body, one of many Palestinians held by the Israeli occupation authorities.

To cope with her pain, early in the morning before going to work, Azhar visits an open grave of her son Abdul Hamid in Bethlehem.

With Mother's Day on March 21, Azhar feels Abdel Hamid's loss and smile, but insisted that the occasion be celebrated only when his body is buried in the grave in Bethlehem.

The story dates back to April 18, 2016, when televised images showed smoke rising from two burning buses in an area southwest of Jerusalem near the border with the occupied West Bank as a result of an attack that injured 20 people.

Reuters quoted a pro-Hamas website as saying that the perpetrator of the attack was Abdul Hamid Abu Srour, and that he died of his wounds after an attack on an Israeli passenger bus in Jerusalem, while his family denies this.

Mother Azhar says her son's body was taken to one of Israel's "cemeteries of numbers" where Palestinian attackers were buried and identified by numbers. Israel sees these areas as closed military outposts, while Azhar's family is one of many demanding the return of the remains of relatives held by Israel.

At a march in Ramallah on Mother's Day, mothers and relatives of Palestinians whose bodies are being withheld by the Israeli authorities took to protest against the measure, which Palestinians and human rights groups consider "collective punishment".

Israel sees this as a means of deterrence and stopping any future attacks, but Azhar says this will only increase "resistance against the occupation," and that "all the crimes of the occupation were not a deterrent to the Palestinian people, but rather increased their determination and will."
