Baghdad - US President Barack Obama called on Wednesday for an international front against jihadists in Iraq and Syria after they beheaded a second American reporter, as Britain and France weighed military action.
"We know that if we are joined by the international community, we can continue to shrink ISIL's sphere of influence, its effectiveness, its financing, its military capabilities," said Obama, referring to the Islamic State (ISIS).
"And the question is going to be making sure we've got the right strategy, but also making sure that we've got the international will to do it," he said in Estonia's capital Tallinn.
Military response
Britain, with one of its nationals also under threat of beheading, said it would not rule out taking part in air strikes if necessary.
"I can assure you that we will look at every possible option to protect this person," Foreign Secretary Philip Hammond said.
And French President Francois Hollande likewise raised the prospect of a military response to the threat posed by IS.
"The head of state underlined the importance of a political, humanitarian and if necessary military response in accordance with international law" to fight against IS, the presidency said.
Obama pledged that justice would be done to the killers of 31-year-old reporter Steven Sotloff, wherever they hid and however long it took.
Foreign fighters
Obama will lead a UN Security Council session on the threat of foreign fighters in Iraq and Syria on 25 September, a US official said on Wednesday.
His Secretary of State John Kerry revealed he was working to forge a global coalition to fight the "medieval savagery" of Islamic militants terrorising a swathe of Syria and Iraq.
IS on Tuesday posted video footage on the Internet of Sotloff's beheading, confirmed as authentic by Washington, sparking outrage around the world.
It said the journalist's killing, which came on the heels of the beheading last month of another US reporter, James Foley, was in retaliation for expanded US air strikes against its fighters in Iraq during the past week.
It warned that a British hostage would be next unless London backs off from its support for Washington's air campaign.
'Act of savagery'
Obama said Washington was determined to halt the IS threat but warned it would depend on close co-operation with partners in the region.
The United Arab Emirates voiced its readiness to "take needed measures", as Iraq condemned the beheadings as "an act of savagery and evil" that showed the urgency of defeating the jihadists.
British Prime Minister David Cameron said the beheading video depicted an "absolutely disgusting, despicable act" and chaired a meeting of security chiefs to discuss how to tackle the IS threat.
The masked executioner in the video spoke with a London accent and claimed to be the same man, confirmed by UK security services as a Briton, who beheaded Foley.
"I'm back, Obama, and I'm back because of your arrogant foreign policy towards the Islamic State," the black-clad jihadist says, wielding a combat knife.
"So just as your missiles continue to strike the necks of our people, our knife will continue to strike the necks of your people," he declares, before reaching round to cut his captive's throat.
At the end of the five-minute recording, the militant threatens another captive, identified as Briton David Cawthorne Haines.
London has maintained a media silence about the kidnapping of the aid worker and there were few immediate details about when or how he was abducted.
Britain has so far only carried out reconnaissance flights in support of the US air campaign from its base in Cyprus.
A voice for the voiceless
Sotloff's family paid moving tribute to the 31-year-old reporter, remembering a gentle soul with a fondness for junk food and golf who was fiercely committed to giving "a voice to those who had none."
"He was no war junkie, he did not want to be a modern-day Lawrence of Arabia: he merely wanted to give voice to those who had none," Sotloff family spokesperson Barak Barfi said in a statement.
Israeli media reported that the family was Jewish and that Sotloff himself held joint US-Israeli nationality but IS made no mention of either in its video.
Sotloff's former employers at Time and Foreign Policy paid tribute to a man widely respected for his intrepid reporting in Syria and the wider region, including a previous stint in Libya.
Hours after the posting of the video, the White House announced that Obama had authorised about 350 more US troops to beef up security at US diplomatic facilities and protect personnel in Baghdad.
