Rochester, New Hampshire -

The mother of slain US journalist James Foley says she hopes the killing of a second American in Syria will galvanise world leaders to find peaceful solutions to global conflicts.

Diane Foley, of Rochester, New Hampshire, told New England Cable News on Wednesday that she had hoped Steven Sotloff and other captives held by the Islamic State group in Syria would be spared.

A video posted on Tuesday showed a member of the militant group beheading Sotloff.

A video released two weeks ago showed James Foley being killed the same way.

Diane Foley said she sends her deepest condolences to the Sotloff family and says “we are just heartbroken for them”.

She says she hopes the worldwide outrage over the killings is “funnelled into goodness and peace”. - Sapa-AP
