BEIRUT (AP) There can be no financial bailout for Lebanon, a senior U.S. official said Saturday, calling on the countrys political leaders to heed popular calls for change, real reform and an end to endemic corruption.

David Hale, U.S. undersecretary of state for political affairs, said the U.S. and its allies will respond to systemic reforms with sustained financial support. He also called for a thorough and transparent investigation into the Aug. 4 blast that killed nearly 180 people and wounded thousands.

He said an FBI team is arriving this weekend to take part in the probe at the invitation of Lebanese authorities.

Hale arrived in Beirut on Thursday, where he met with volunteers helping out at the site of the blast, as well as the countrys top political and religious leadership.

America calls on Lebanons political leaders to finally respond to the peoples longstanding and legitimate demands and create a credible plan accepted by the Lebanese people for good governance, sound economic and financial reform, and an end to the endemic corruption that has stifled Lebanons tremendous potential, he said.

But as the dozens of young activists and volunteers I met so bluntly demanded, there can be no bailout, Hale said in a recorded message posted on the U.S. Embassy website Saturday.
