Prominent Syrian Kurdish activist and politician Mish'al at-Tammo has been shot dead on Friday evening in the Kurdish city of Qamishli in western Kurdistan [northeastern Syria].

Activists and residents at Qamishli say that gunmen had attacked his residence home in the city and shot him dead before his corps was moved to Faraman private Hospital in al-Qamishli.

They also added that Mr Tammo's son, Marcel, was put at emergency room and is suffering from fatal injuries as he was accompanied his father Mish'al the time gunfire took place.

Reports said that this is the second attempt to kill the Syrian Kurdish activist Mish'al Tammo.

Syrian HR says "responsibility for the killing lies with the Syrian regime, whether their forces killed him, or he was killed by others – the Government has a duty of care towards its citizens".

The US state department blamed the Syrian authorities for the deaths, reportedly calling the killing a "clear escalation of regime tactics".

Another female activists Zahidh Reshkilo was also injured and moved to hospital at the same attack which targeted Tammo house.
