ISTANBUL: Turkey on Tuesday said it had no confirmation of a video published by IS purportedly showing the burning to death of two Turl(ish troops captured in Syria.

After users in Turkey reported problems using social media in the wake of the release of the video, Deputy Prime Minister Numan Kurtulmus said some media needed to `watch their step` in the face of attempts by terror groups to spread fear.IS militans last week circulated a video purportedly showing two Turkish soldiers captured by the extremists in Syria being burned alive.

`There is still no clear information from our armed forces or defence ministry to confirm these video images,` Kurtulmus told reporters in Ankara in televised comments. `1f there is confirmed information, it will be shared with the public,` he said.

But Kurtulmus addedthat terror groups were `vile mechanisms` and were seeking to `spread desperation` through fear.

`In particular social media is not the place for irresponsible publications, he said, warning that `some friends in the media should please watch their step` `Turkey is at the moment in a de-facto war with Daesh [IS],` he added.

After the video was first published late on Thursday, Turkey`s Defence Minister Fikri Isik said threeTurkish soldiers were currently being held by IS, without giving further details.

Users in Turkey had reported severe problems with social media after the video emerged and the Turkey Blocks monitoring network said it had confirmed a `throttling` of Twitter and YouTube affecting many users.

However, by Monday access to Twitter was fully restored after some three days of disruption.-AFP
