The European Union said Monday it remains "fully committed" to tackling the threat posed by ISIL after it beheaded US aid worker Peter Kassig, but kept mum on the beheading of the other 18 Syrian soldiers whom were also beheaded by the same group.
  
EU foreign policy chief Federica Mogherini and humanitarian aid commissioner Christos Stylianides said in a statement that the killing of Kassig and 18 Syrian military personnel showed ISIL’s "resolve to pursue its terror agenda in breach of all universally recognized values and rights."
  
"All perpetrators of human rights abuses must be held accountable. The EU will spare no effort towards this objective," they said in their statement. "We remain fully committed to tackling the threat posed by ISIL and other terrorist organizations in Syria and Iraq, alongside our regional and international partners."
  
A video released by ISIL terrorists showed the beheading of Kassig, who took the name Abdul-Rahman after converting to Islam, and that of 18 men described as Syrian military personnel.

Kassig's death was confirmed by President Barack Obama.
  
The 26-year-old was captured last year and was threatened in an October 3 video showing the beheading of British aid worker Alan Henning.
