The United States will seek for new sanctions by the United Nations Security Council against Iran as the latter refuses to give up its nuclear program in the latest talks with officials of the European Union, the State Department said Friday.

"They (Iranians) have not agreed to suspend their uranium enrichment activities as they are required to do under Security Council resolutions," State Department deputy spokesman Tom Casey said.

"I suspect this will mean we will be starting very soon with some consultations on developing the next round of sanctions through a new UN Security Council resolution," he said.

Casey made the remarks after EU foreign policy chief Javier Solana and top Iranian negotiator Ali Larijani had talks on Iran's nuclear issue in Madrid, Spain Thursday.

The UN Security Council has adopted two resolutions imposing financial and other sanctions on Iran over its refusal to suspend uranium enrichment, a process which can either be used to generate electricity, or to make nuclear weapon.

The United States and its Western allies have accused Iran of trying to develop nuclear weapons under the cover of its civilian nuclear programs.
