Amman: Islamic State militants have abducted at least 150 people from Assyrian Christian villages in north-eastern Syria they had raided, Christian Syrian activists said on Tuesday.

A Syrian Christian group representing several NGOs inside and outside the country said it had verified at least 150 people missing, including women and the elderly, who had been kidnapped by the militants.

"We have verified at least 150 people who have been abducted from sources on the ground," Bassam Ishak, president of the Syriac National Council of Syria, whose family is from the north-eastern town of Hasaka, said from Amman.

Earlier the British-based Syrian Observatory for Human Rights said 90 were abducted when the militants carried out dawn raids on rural villages inhabited by the Christian minority west of Hasaka, a city mainly held by Kurdish militias.
