Western and Middle Eastern countries in the coalition are meeting this week in Paris. Abadi is on a visit to Paris to take part in a meeting on ISIS and win international support in the fight against the terrorists.
"ISIS's advance in the region presents failure and defeat for the whole world," the Iraqi prime minister said, addressing a press conference in Paris on Tuesday.
Al-Abadi underlined that Iraq needs support of the whole world to combat the Takfiri terrorists, "but, we are not getting much; there are a lot of talks about support for Iraq, there is very little on the ground."
"What I can see for Iraq, the flow of foreign fighters is more than before," he added.
Senior Iraqi officials have blamed Saudi Arabia, Qatar, and some Persian Gulf Arab states for the growing terrorism in their country.
The ISIS has links with Saudi intelligence and is believed to be indirectly supported by the Israeli regime.
