A Syrian journalist who was shot in the Turkish city of Gaziantep in an attack claimed by the Islamic State group has died from his wounds.

Mohammed Zahir al-Sherqat died on Tuesday afternoon in a hospital in Gaziantep, near the Syrian border, according to his friend Barry Abdulattif, a Syrian activist.

Sherqat, who worked for Halab Today TV, was shot in the neck from close range on Sunday while walking on a street.

Friends told the AP that the journalist had received death threats as recently as two months ago from IS extremists.

IS claimed the attack on Monday via the IS-affiliated Aamaq news agency, which said Sherqat "used to present anti-Islamic State programs."

It marks the fourth assassination of a Syrian journalist in Turkey claimed by the extremist group.
