After the September 2000 outbreak of the Second Intifada, negotiations continued at the Taba summit in January 2001; this time, Ehud Barak pulled out of the talks to campaign in the Israeli elections. In October and December 2001, suicide bombings by Palestinian militant groups increased and Israeli counter strikes intensified. Following the election of Ariel Sharon in February, the peace process took a steep downfall. Palestinian elections scheduled for January 2002 were postponed—the stated reason was an inability to campaign due to the emergency conditions imposed by the Intifada, as well as IDF incursions and restrictions on freedom of movement in the Palestinian territories. In the same month, Sharon ordered Arafat to be confined to his Mukata'a headquarters in Ramallah, following an attack in the Israeli city of Hadera; US President George W. Bush supported Sharon's action, claiming that Arafat was "an obstacle to the peace."
