The United States is developing a plan to send US troops to rescue Iraq's Yazidis, currently under siege by forces of the self-proclaimed Islamic State (IS). The plan, which has yet to be submitted to and approved by President Obama, comes amid growing pressure on the US and other Western nations to intervene directly in Iraq to prevent a massacre of the Yazidi minority and to help Kurdish forces repel IS.

A US rescue mission would risk putting American forces into direct conflict with IS fighters, but US officials warn such a move might become necessary if supply drops by Western powers to the Yazidis, currently under siege on Mt. Sinjar in northern Iraq, prove insufficient. "You can only do that for so long," one official told The Wall Street Journal.

On Tuesday, the US sent another 130 military advisers to Iraq to assess the situation on the ground, which will help the Pentagon determine what it can do next. The team includes US Marines and special operations forces who have expertise in such situations. The Wall Street Journal notes that despite ongoing media coverage, much about the situation around Mt. Sinjar remains unclear, including just how many Yazidis are in peril there 鈥� reports range from several thousand to as many as 50,000 refugees present. Given the uncertainty and聽the difficulty of operations in mountain terrain,聽the scope of a rescue mission still has to be worked out.

"Any operation with respect to the mountain has its challenges," the US official told The Wall Street Journal. "Whether you try to do something by air, whether you try to do something by ground, both have inherent risks to them."

The development of the plan comes amid increasing calls from the Kurdish government and Yazidi leaders for the US to respond more forcefully against IS militants. Al Jazeera reports that Kurdish leaders say that US airstrikes, which the White House has described as limited, are not enough.

The Daily Beast notes that while the CIA has already begun covertly supplying the Kurds with arms, the Kurds have also asked specifically for drones and other advanced weaponry, including "Javelin anti-tank missiles, integrated air defense systems, armored personnel carriers, surveillance drones, and third-generation night vision equipment."

The Yazidis have also pleaded for more assistance from the West, 海角大神 reports.

The British government, which has been dropping supplies to those on Mt. Sinjar and has deployed Chinook helicopters to the region, is also feeling pressure to step up its efforts. The Guardian reports that former Conservative Foreign Secretary Liam Fox called for Britain to do more, writing in the Daily Mail, "The idea that this is not our problem is wishful thinking at best, and catastrophic complacency at worst. The US government has made a belated, but welcome, decision to use American air power to hit Isis bases. We should be willing to do the same if asked."

Similarly, Col. Tim Collins, whom the Telegraph describes as "one of Britain鈥檚 most respected commanders," argued that the aid drops were little more than 鈥渁 pebble in the ocean.鈥�

British Prime Minister David Cameron has said that Britain would not intervene militarily in Iraq, and its assistance would be limited to aid drops.
