STOCKHOLM (AP) - WikiLeaks founder Julian Assange has filed another appeal against a court order to detain him in a rape investigation, Swedish officials said Tuesday.

The appeal was received by the Supreme Court in Stockholm on Tuesday, court spokeswoman Tove Levelind said.

Earlier this month, an appeals court rejected Assange's first appeal, upholding a district court decision to detain him for questioning.

Assange, whose whereabouts are unknown, is wanted by Sweden internationally concerning allegations against him that include rape and sexual molestation. They stem from his encounters with two Swedish women during a visit to the Nordic country in August.

He has denied the allegations, calling them part of a smear campaign. He has not been formally charged.

WikiLeaks made another disclosure of classified documents over the weekend, including diplomatic cables and sensitive U.S. State Department documents.

The 39-year-old Australian has angered the U.S. and other governments with such disclosures, including secret documents about the wars in Afghanistan and Iraq.

During his August visit to Sweden, Assange applied for a residency permit in the country, where the WikiLeaks site has some of its servers and laws offer strong protection for whistle-blowers. Sweden rejected the request.
