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.

The man on the audio claimed to be Fuad Mohamed Khalaf, considered by the State Department to be Al-Shabaab's leading fundraiser. The United States has offered $5 million for information of his whereabouts.

"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.

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.
