Islamic State militants tightened their noose on a northern
Syrian border town on Sunday as the United Nations said the
number of Syrian Kurds fleeing into neighbouring Turkey may
have topped 100,000 and was likely to go much higher.
About 60,000 Syrian Kurds have crossed into Turkey in 24
hours, a deputy prime minister said, fleeing an advance by
Islamic State militants who have seized dozens of villages
close to the border and are advancing on a Syrian town.
