Israel must investigate the “unlawful” killing of 11 civilians carrying white flags during its Gaza operation earlier in 2009, Human Rights Watch has said.

Five women and four children were among those killed in seven incidents detailed by the US-based rights group.

Researchers said the soldiers at best failed to protect civilians, and at worst deliberately shot at them.

Israel has launched investigations into five “white flag” incidents, but says Hamas exploited civilians with flags.

In one incident, east of Jabalya, HRW said Israeli soldiers fired at two women and three children, three of whom were holding pieces of white cloth.

Two girls, aged two and seven were killed, and another, now aged four, was left paralysed below the waist.

The five were standing outside their home after an Israeli soldier had ordered them to leave it, HRW said.
