1 woman killed in Istanbul airport blast

A female cleaner was killed and another wounded early today after an explosion of unknown origin beside a plane at Istanbul's second international airport, with Turkey on high alert for possible attacks.
Airport cleaner Zehra Yamac, 30, died of head wounds hours after the pre-dawn blast on the tarmac at Sabiha Gokcen airport on the Asian side of Turkey's largest city, the state- run Anatolia news agency reported.
The explosion took place just outside the terminal building where planes park for their passengers to embark and disembark.
Turkey's private carrier Pegasus Airlines said in a statement the explosion took place next to one of its planes on the tarmac while the two cleaners were nearby.

"There were no passengers either on the plane or on the stairway. Sabiha Gokcen airport is continuing its normal operations," Pegasus said.
The wounded victim, also a cleaner, was hurt in the leg. Yamac was hospitalised but died of her wounds despite the efforts of medical staff, Anatolia said.

The airport said in a statement on its official Twitter account that "flights from our terminals are continuing according to schedule."
Sabiha Gokcen airport, named after Turkey's first female fighter pilot, is the second international airport in Istanbul after much larger Ataturk Airport on the European side of the city.
Sabiha Gokcen hosts flights both to domestic and numerous international destinations often with budget airlines but also from Turkey's flag carrier Turkish Airlines.

"We are working very closely with the Turkish government and our counterparts to facilitate the investigation, and we await their official report on it," Dato' Azmi Murad, the executive director of Sabiha Gokcen, said in a statement.
"The Turkish government has heightened security within the vicinity of the airport, which includes helicopter surveillance," he added.
According to Azmi, the airport resumed "normal flight operations" around two hours after the blast.
The Dogan news agency said that three planes up to 350 metres away from the site of the blast had sustained damage.
Police stepped up security at airport entrances after the blast, searching vehicles while a police helicopter circled overhead, Anatolia said.

Turkey is on alert after 103 people were killed on October 10 when two suicide bombers ripped through a crowd of peace activists in the capital Ankara, the worst attack in modern Turkey's history.
