Israel must expel Yasser Arafat and should not necessarily be deterred by U.S. objections, the Israeli foreign minister said Thursday, ahead of a crucial government debate on the fate of the Palestinian leader. Prime Minister Ariel Sharon, who cut short a visit to India, was to convene his security Cabinet later Thursday to decide on an Israeli response to the latest Hamas suicide bombings - two attacks that killed 15 Israelis on Tuesday. Strategic decisions are on the agenda, including Arafat's expulsion and a reoccupation of the Gaza Strip, where Hamas leaders are based.
