Annie Lennox has called for an end to the violence in Gaza, which has now entered its seventh day.
The former Eurythmics singer said she had been “shaken to the core” by footage of the conflict.
More than 400 people are believed to have been killed since Israeli forces launched a bombing campaign against the leaders of the Palestinian Sunni paramilitary organisation Hamas last week.
Speaking at a press conference in London, Lennox said: "A few days after Christmas I came downstairs, put the television on and saw smoke pyres emanating from buildings and it shook me to the core.
"I was thinking, as a mother and as a human being, how was this going to be a solution to peace?
"It's a question of human rights, human values that goes beyond Jewish, Muslim, nothing to do with any of that. Therehas to be a place ultimately where people come to the table."
The latest violence, which has threatened to derail any hope of peace in the Middle East, was triggered after Hamas began firing rockets into Israel.
Respect MP George Galloway and Bianca Jagger have also called for a ceasefire.
