Extent of liability

As to any claim for relief with respect to which a foreign state is not entitled to immunity under section 1605 or 1607 of this chapter, the foreign state shall be liable in the same manner and to the same extent as a private individual under like circumstances; but a foreign state except for an agency or instrumentality thereof shall not be liable for punitive damages; if, however, in any case wherein death was caused, the law of the place where the action or omission occurred provides, or has been construed to provide, for damages only punitive in nature, the foreign state shall be liable for actual or compensatory damages measured by the pecuniary injuries resulting from such death which were incurred by the persons for whose benefit the action was brought.
