A leading Syrian Kurdish politician was killed early Tuesday after a car bomb blew up outside his home near the northern border with Turkey, a pro-Kurdish news agency reported.
Isa Huso, a member of the Supreme Kurdish Council diplomacy committee was assassinated as he left his house in the Syrian Kurdish city of Qamishli, the Firat news agency reported.
Huso, 60, had worked for Kurdish freedom and actively participated in the founding congress of the Kurdish Democratic Union Party (PYD), the main Syrian Kurdish party, which is also considered a branch of Turkey's outlawed Kurdistan Workers' Party (PKK).
The report did not say who is believed to be responsible for the killing.
Huso had reportedly been imprisoned several times under the rule of Syrian President Bashar al-Assad's for campaigning against human rights abuses.
Responding to Huso's killing, Kurdish fighters known as the Popular Protection Units (YPG) issued a call to arms.
"(The YPG) called on all those fit to carry weapons to join their ranks, to protect areas under their control from attacks by Islamic State of Iraq and the Levant (ISIS) fighters, Al-Nusra Front and other battalions," a London-based Syria watchdog, the Syrian Observatory for Human Rights, said, according to the BBC.
