The United States has offered a reward of $10m (£6.3m) for information leading to the arrest of a man they say is a key al-Qaeda facilitator and financier.

美国悬赏1000万美元征集能够逮捕某男子的线索，该男子据称是基地组织的推进者和资助人。

Yasin al-Suri, the US state department said, is a Syrian operating from Iran.

The bounty¹ aims to disrupt a financial network that, it said, has operated from within Iran's borders since 2005.

State department official Robert Hartung said it was the first time a "terrorist financier" has been targeted in such a way.

"He is a dedicated² terrorist working in support of al-Qaeda with the support of the government of Iran," Mr Hartung said, according to AP.

"As a key fundraiser for the al-Qaeda terrorist network, he is a continuing danger to the interests of the United States."

He added that Mr al-Suri - who is also known as Ezedin Abdel Aziz Khalil - operated under an agreement between al-Qaeda and the government of Iran, moving money and recruits（征募） through the country to the network in neighbouring countries - specifically Afghanistan, Pakistan and Iraq.

He was blacklisted along with five other members of his network by the US treasury³ department in July.

Mr Hartung said that, since 1984, the US Rewards for Justice programme has paid more than $100m to more than 70 people who provided credible⁴ information that either prevented attacks or helped bring those accused to justice.
