Israel: Along with its foreign minister, Israel has sent doctors, social workers, trauma specialists and security experts to Turkey in the wake of Saturday's bombings at two Istanbul synagogues - underlining the profound sense in Israel of a common fate with the victims, especially the targeted Jewish community.
Several of the Orthodox Jewish volunteers who collect body parts at bomb sites in Israel for Jewish burial also flew in.
Israeli officials, including Prime Minister Ariel Sharon, say the attacks are proof that no country is immune from terrorism and are as a consequence of rising anti-Semitism. They are urging the international community to confront both phenomena.
Some Israeli officials are also suggesting that Israeli and other Jewish tourists around the world might want to "lower their profile", to avoid being easily targeted.
"It would be wise to remove major overt signs of Jewishness," said Mr Yitzhak Levy, a former head of security for the Shin Bet domestic intelligence service.
Sending condolences to "the families of those slain, Jews and Muslims, members of all faiths," Mr Sharon said the bombings were evidence that "terrorism doesn't discriminate by religion or blood". Indeed, while six of the 23 victims were Jewish, the majority were Moslem. "The aim of terrorism is one - to sow fear and terror through the slaying of innocent people," he said. Mr Sharon also telephoned the Turkish chief rabbi to express sympathy and solidarity.
The Israeli foreign minister, Mr Silvan Shalom, who flew to Istanbul and met with Turkish government officials and Jewish community leaders, said Israel expected "the entire international community to strongly condemn \ terrorist acts and to use all means at its disposal to bring the perpetrators to justice."
Mr Shalom is flying on to Belgium and Austria for talks with EU leaders on a flurry of anti-Semitic comments and anti-Israeli poll findings, which he says he regards as part of the context both of Saturday's attacks and a series of others aimed at Jewish targets in Morocco, France and elsewhere.
Israeli officials are denying Turkish newspaper reports that the Mossad issued specific warnings to the Turkish authorities in recent weeks about imminent bombings, although Israel's consul-general, Mr Amira Arnon, said that "non-specific" warnings had been received.
