CNN) -- The United States offers millions for information leading to the capture of the world's most wanted terrorists.
A Somali militant group has purportedly countered with an offer of camels for U.S. officials.
Al-Shabaab has placed a bounty of 10 camels for President Barack Obama and two camels for information on Secretary of State Hillary Clinton.
An audio statement posted on jihadist websites purportedly from Al-Shabaab jeered news that the United States is offering millions of dollars for information on seven key members of al-Shabaab through its Rewards for Justice program.

"Whoever brings the mujahidin information about the whereabouts of infidel Obama and the lady of Bill Clinton, the woman named Hillary Clinton, I will give a reward," the man said.
A study by Galkayo University, which looked at the effects of drought on livestock, said the average cost of a camel in Somalia is $700.
CNN can not independently verify the authenticity of the audio recording, which was purportedly made by Khalaf during a speech to followers in the southern port city of Merca.
The U.S. State Department's Rewards for Justice program is offering $7 million for information on the location of Ahmed Abdi Aw-Mohamed, the founder of the Islamist group in Somalia.
This year, he and al Qaeda's leader, Ayman al-Zawahiri, released a joint video formally announcing a merger between the terror groups.
In announcing the bounties on Mohamed and his key associates Thursday, the State Department called al-Shabaab "a threat to the stability of East Africa and to the national security interests of the United States."
The State Department said it is also offering up to $5 million each for information leading to the location of four of Aw-Mohamed's associates, including Khalaf. In addition, it is offering up to $3 million each for two of the terror group's other leaders
