Mrs. Robinson went on to point out that Israel, as a democratic society, "must not abandon its core standards and values, even in the face of the serious security threat to its own civilian population".
She added that the assassination policy being pursued by Israel is in conflict with democratic standards and unlawful under international law.
The High Commissioner, who has strongly condemned suicide bombings against Israeli civilians, said she was worried the air attack would serve to feed the ongoing violence.
"The current cycle of savagery must end", she said. "In the eyes of the world, this requires responsible action from both sides of this tragic conflict".
