JERUSALEM (Reuters) -Israeli Foreign Minister Gideon Saar accused unnamed European officials on Thursday of "toxic antisemitic incitement" he blamed for a hostile climate in which the fatal shooting of two Israeli embassy staffers in Washington took place. Israel has faced a blizzard of criticism from Europe of late as it has intensified its military campaign in Gaza, where humanitarian groups have warned that an 11-week Israeli blockade on aid supplies has left the Palestinian enclave on the brink of famine. Saar did not name any countries or officials but said the climate of hostility towards Israel was behind the shooting of the embassy staffers Yaron Lischinsky and Sarah Lynn Milgrim outside a Jewish museum in Washington on Wednesday.
