The new UN envoy to Syria has called for an urgent international response to the assault by Islamic State militants on a strategic Kurdish Syrian town on the Turkish border.
Staffan de Mistura said the world will "regret deeply" if Kobani falls to IS after defending "itself with courage."
His comments on October 7 come as the U.S.-led coalition carried out more air strikes to halt the IS advance on Kobani.
According to the Syrian Observatory for Human Rights, Kurdish forces on October 7 managed to push back IS militants from some areas on the eastern edges of Kobani.
Thousands across Turkey's mainly Kurdish southeast have taken to the streets to demand a tougher Turkish response.
Turkish news agencies said at least 14 people died and scores were injured in clashes between Turkish police and Kurdish protesters on October 7.
Meanwhile, Canada's parliament has voted to authorize air strikes against Islamic State in Iraq following a U.S. request.
Prime Minister Stephen Harper's Conservative Party introduced the motion last week and it was debated this week.
Harper has a majority of seats in parliament so the vote was all but assured.
The motion passed 157-134 on October 7.
The motion authorizes air strikes in Iraq for up to six months and states that no ground troops be used in combat operations.
Canada is among dozens of countries that have joined the U.S.-led coalition fighting the Islamic State militant group.
