POTSDAM, Germany (AP) _ President Clinton today ordered tough sanctions against India in retaliation for its underground nuclear tests. The United States acted as India said it had conducted two more nuclear tests.

Clinton was to announce the sanctions after talks with German Chancellor Helmut Kohl. He executed the necessary paperwork this morning before flying here from Berlin to meet Kohl, senior officials said.

The sanctions include an end to U.S. assistance to India, a prohibition on the export of certain defense and technology material, an end to U.S. credit and credit guarantees to India, and U.S. opposition to lending by international financial institutions to India, the officials said. While U.S. assistance is to be halted, there is an exception for food and humanitarian aid.

Clinton has condemned India's nuclear tests. Under U.S. law, sanctions are mandatory.
