According to the official, Jordan accounted for around 20 percent of the anti-Islamic State coalition attacks carried out so far.
"We are determined to wipe them [Islamic State] from the face of the Earth," Jbour said, as quoted by the BBC.
Nearly 20 percent of insurgents' capabilities were degraded in attacks, concentrated on the Syrian city of Raqqa, a stronghold of the Islamic extremists.
"We achieved what we aimed at," Jbour said.
On Saturday, the United Arab Emirates deployed a squadron of F-16 fighter jets in Jordan to support its mission in the US-led coalition against jihadists.
The Islamic State is an insurgent group that has captured large areas of Syria and Iraq, and proclaimed a caliphate on the regions under its control. The group is infamous for human rights atrocities, including executions of foreign nationals.
A coalition of more than 60 countries led by the United States has been carrying out airstrikes on militants' positions in an attempt to end their advance.
