ISIS in crosshairs of growing coalition amid new strikes

A human rights group says airstrikes hit targets of the Islamic State of Iraq and Syria, or ISIS, and other extremist targets in eastern Syria Saturday morning.

CBS News' Julianna Goldman reports that the Obama administration says the world is united against ISIS after a critical week rallying the international community at the United Nations and launching the expanded air campaign in Iraq and Syria.

But the Pentagon is warning that even with new commitments from important allies, the coalition is just at the beginning, not the end, of this fight.

"The hallmarks of this campaign will be patience and persistence, not shock and awe," British Prime Minister David Cameron told Parliament.

After pleas from Cameron - and six hours of debate - Britain's lawmakers voted overwhelmingly to take part in the U.S.-led coalition against ISIS.

With the commitments growing, America's closest European ally is joining France and the Netherlands as well as Denmark and Belgium, two countries who also said Friday they would provide their military resources.

The European support does not extend to Syria, but the White House says it's important progress.

"There is broad effort underway to build this international coalition," said press secretary Josh Earnest, "and we are pleased with the pace of this coalition's growth, and we're pleased with the strong ties among the United States and countries around the world."

Five Arab nations have partnered with the U.S. to destroy ISIS in Syria. They are Saudi Arabia, the United Arab Emirates, Jordan, Bahrain and Qatar.

With tens of thousands of refugees fleeing across the Turkish border from Syria, Turkey's president said Friday that his country is considering lending its support to the coalition - possibly militarily.

In Washington, Chairman of the Joint Chiefs of Staff Martin Dempsey told reporters that this week's strikes disrupted the militant group's command and control operations in Syria.

He's sticking to his statement from earlier this month that he may eventually recommend the president send ground troops to defeat ISIS, also known as the Islamic State of Iraq and the Levant, or ISIL, but that force wouldn't have to be Americans.

"The president gave me a mission, destroy ISIL," Dempsey said, "and I will recommend to him what it takes to destroy ISIL."

Dempsey said it's too soon to tell if any ISIS or Khorasan group leaders have been killed in the airstrikes so far.

He also said the new campaign is going to mean budget problems for the Pentagon.
