Palestinian families in Arab east Jerusalem held receptions Saturday to mark the 40th day of mourning since their relatives were killed in the Temple Mount shootings.

At Abdel Rahman Kashour's house in the walled Old City, a white flag flew outside instead of a traditional black flag. Kashour's 19-year-old son, Burhan, was by Arab accounts the first to be killed when police opened fire on the mount Oct. 8, killing at least 17 Palestinians."This is the day of a wedding, not mourning," said Kashour, a 62-year-old electrician, explaining the white flag. He said his son was nicknamed the "bridegroom of al-Aqsa" after the revered mosque atop the mount, the third holiest shrine in Islam.

The flag was decorated with an Islamic saying: "There is no God but one God."

An Israeli government investigation blamed Palestinian stone-throwers for the riot. But it criticized police commanders for their failure to anticipate trouble and said there were instances of "unsupervised" gunfire.

There has been a shake-up within the police, but no disciplinary action was taken against officers mentioned in the report.

The Temple Mount is known to Arabs as Haram es-Sharif, or "Noble Sanctuary." Tradition says Prophet Mohammed ascended to heaven from the spot. It is also revered by the Jews as the site of their ancient Temple, destroyed by the Romans.
