Multiple front wars are hard to win:
"Iraqi Security Forces (ISF) recaptured the city of Hit in Anbar Province, western Iraq from ISIS on April 14 as part of ongoing operations to secure the Euphrates River Valley." However ISIS has also had success:
"Despite these losses, ISIS seized additional territory in the Yarmouk Camp District from Syrian al Qaeda affiliate Jabhat al Nusra on April 18, and reclaimed terrain along the Syrian-Turkish border on April 14." (

Given the overall picture painted by the sourced webpage and CNN article, things appear to be going not so good for ISIS.
