In August 2003, Libya accepted responsibility for "the actions of its officials" in respect of the bombing Pan Am Flight 103, but was silent on the question of the Pan Am Flight 73 hijacking. Libya offered US$2.7 billion in compensation to the families of the 270 victims of Pan Am Flight 103 and, in January 2004, agreed to pay $170 million to the families of the 170 UTA victims. The seven American UTA victims' families refused the offer and instead filed a claim for $2.2 billion against Libya. From 2004 to 2006 the U.S. and UK opened up relations with Libya, including removing sanctions and removing the country as a sponsor of terrorism.
