A government commission said Panama's banks can immediately resume some operations suspended nearly two months ago, but customers will not be allowed to withdraw much-needed cash.

The National Banking Commission said Monday that banks can resume offering a dozen services that were suspended following the imposition of U.S. economic sanctions aimed at ousting strongman Gen. Manuel Antonio Noriega.In another development, an opposition leader said Monday that a group of Panamanian dissidents is planning to undertake a military operation against Noriega by the beginning of next week.

Ambassador Juan B. Sosa, who has maintained his loyalty to ousted President Eric Arturo Delvalle, told reporters the group is made up of officers who have supporters in the Panamanian Defense Forces.

Sosa gave no details.

A coup attempt against Noriega last month was put down quickly.
