US Delivering Critical Emergency Aid to Lebanon VOA News The United States is delivering emergency aid to Lebanon, starting with food, water, and medical supplies, under the direction of President Donald J. Trump following Tuesday's blast in Beirut, national security adviser Robert C. O'Brien said Friday. In addition, the U.S. will continue to work with authorities in Lebanon to identify further health and humanitarian needs and will provide further assistance. The U.S. Agency for International Development is deploying a disaster assistance response team to help coordination and delivery of assistance, the statement said. The Trump administration has initially pledged more than $17 million in disaster aid for the country, Secretary of State Mike Pompeo, said, and "will continue to help the Lebanese people as they recover from this tragedy." In addition to providing aid, Pompeo said, the U.S. is joining other nations in the call for "a thorough and transparent investigation" into the cause of the explosion. United Nations rescue workers searched the wreckage for survivors Friday. French and Russian rescue teams with dogs also searched the area Friday. Lebanese authorities believe that 2,750 tons of ammonium nitrite stored in warehouses for the last six years led to the explosion of this week. .
