Turkish man, 20, carried out Syria border bombing: Official

A 20-year-old Turkish man reportedly linked to Islamic State militants carried out the suicide bombing in the mainly Kurdish town of Suruc near the border with Syria that killed 32 people this week, a Turkish official said on Wednesday.

"As a result of DNA tests, we confirm that the assailant is a 20-year-old man registered in Adiyaman," the official told AFP on condition of anonymity, referring to a province in southeastern Turkey.

Media reports had earlier said the man - identified by his initials SAA - had first become involved with IS militants two months ago.

Turkish authorities are also reportedly investigating if a female corpse found after the Suruc bombing which could not be identified might be a second suicide bomber. 

Monday's blast ripped through a gathering of activists in Suruc, just across the border from the Syrian town of Kobane which was the scene of fierce clashes between Kurdish forces and militants last year.

Most of 32 dead were university students who gathered in Suruc to prepare for an aid mission in Kobane.

Turkish authorities are also investigating if there is any connection between the latest bombing and a deadly attack in the Kurdish majority city of Diyarbakir last month. That blast killed four people and wounded dozens during a pre-election rally by the pro-Kurdish People's Democratic Party (HDP) on 5 June.  

The Hurriyet newspaper reported on Wednesday that the bomb mechanism used in Diyarbakir and Suruc were similar.

The authorities suspected SAA could have connections with the assailant in Diyarbakir attack, as the two were believed to have joined IS at similar times, it added.

Police found TNT explosives and many iron ball bearings at the blast scene in Suruc, just like the one in Diyarbakir. 

The suspect's affiliation was not officially confirmed but the pro-Kurdish party's co-chair Selahattin Demirtas said the attack was linked to the Islamic State group.
