President Bush on Friday signed a book of condolences for Pakistani earthquake victims, and he offered prayers and humanitarian aid in response to the disaster. At a brief ceremony at the Pakistani embassy in Washington, the president told Ambassador Jehangir Karamat that Pakistan is a friend and America will help in any way it can. After signing the book, President Bush said the American people not only offer their prayers, but offer their help so that Pakistan can get back on its feet. He said Washington has moved a lot of military equipment in the area, and is also helping with humanitarian aid. President Bush committed 50 million dollars in relief aid immediately after last week's quake. U.S. helicopters also are flying relief missions in the affected region.
