The massive daylight airstrike, which was conducted Thursday, involved 16 coalition aircraft that dropped 22 bombs or other munitions on 22 targets, the coalition said in a statement.

The Islamic State seized the heavy weapons and other equipment when they recaptured Palmyra, an archeological gem in central Syria, from Syrian forces earlier this week. The equipment was taken from the Tiyas Military Airfield, a Syrian military post near Palmyra.
