Samra Kesinovic, 16, and Sabina Selimovic, 15, vanished from their homes in Vienna on April 10.
But the first hint their parents received as to where the girls might have gone was a spate of social media posts claiming they had gone to fight a ‘holy war’.
But the parents say that they don’t believe the messages are being written by the girls. Authorities suspect they have been tricked into leaving the country.
Samra and Sabina come from Bosnian refugee families who settled in Austria after the ethnic wars of the 1990s, and were born in the country.
The fighting in Syria continues to be fierce – just today a bomb was detonated in the northern city of Aleppo, destroying buildings and injuring children.
New photos on their Facebook pages show them brandishing Kalashnikov rifles – and in some cases surrounded by armed men.
However, it has since emerged that some of these pictures have been circulated online for years – casting doubt on whether they actually show the girls.
In the latest posting they announced plans to marry so that they could become ‘holy warriors’ and in the messages they say: ‘Death is our goal’.
