Turkish warplanes killed at least 20 ISIS group armed militants as part of Operation Euphrates Shield in northern Syria, Turkey's military said on Thursday. 
In an air operation targeting ISIS held buildings in northern Syria, Turkish jets hit 51 targets, the Turkish Armed Forces said in a statement. 
The targets included shelters, defensive positions, and command and control facilities, the statement added. 
Eight targets in the Al-Bab and Suflaniyah regions were hit by Turkish warplanes, it said. 
An operation began in August 24 to improve security, support coalition forces, and eliminate the terror threat along Turkey's border.
