New York (CNN) -- The federal government said Thursday it is seeking forfeiture of properties belonging to the Alavi Foundation and Assa Corp. -- accused of transferring money to a bank owned by the Iranian government -- including a Manhattan skyscraper and at least three mosques.

Preet Bharara, the U.S. attorney for the Southern District of New York, announced Thursday's filing of an amended civil complaint seeking forfeiture of the Alavi Foundation's interest in the 36-story office tower located on Fifth Avenue in Midtown Manhattan.

The building is owned by 650 Fifth Avenue Company, a partnership between the Alavi Foundation and Assa Corp., the Justice Department said in a news release. The amended complaint alleges that the Alavi Foundation provided services to the Iranian government and transferred money from 650 Fifth Avenue Company to Bank Melli, which is owned and controlled by the government of Iran.

The amended complaint seeks forfeiture of all assets of the Alavi Foundation and Assa Corp., including bank accounts owned by 650 Fifth Avenue Company, the Alavi Foundation and Assa Corp.; and properties owned by the foundation in New York, Maryland, Virginia, Texas and California.

It alleges that the properties were "involved in and [were] the proceeds of money laundering offenses," and that the owners violated the International Emergency Economic Powers Act, executive orders and U.S. Department of Treasury regulations.

"As today's complaint alleges in great detail, the Alavi Foundation has effectively been a front for the government of Iran," Bharaha said. "For two decades, the Alavi Foundation's affairs have been directed by various Iranian officials, including Iranian ambassadors to the United Nations, in violation of a series of American laws. The Alavi Foundation's former president remains under investigation for alleged obstruction of justice, and both the criminal and civil investigations are ongoing."

Calls to a lawyer representing the Alavi Foundation were not immediately returned.

Relations between Iran and much of the international community have been tense over Iran's nuclear ambitions. Iran has said it wants to develop its nuclear program solely for peaceful purposes; the United States and a number of other countries have said they suspect the oil-rich nation is pursuing a nuclear bomb.

In another U.S.-Iran development, President Obama said Thursday in a letter to Congress that the national emergency with respect to Iran that was declared in 1979 during the Iranian revolution has not ended.

"Our relations with Iran have not yet returned to normal, and the process of implementing the January 19, 1981, agreements with Iran is still under way," Obama wrote in an official "notice of continuation" required to extend the emergency status with Iran beyond the anniversary date of November 14. "For these reasons, I have determined that it is necessary to continue the national emergency declared on November 14, 1979, with respect to Iran, beyond November 14, 2009."
