Organisation denies links to al-Qaeda after counter-terrorism officers sweep through, detaining one person.
Turkish counter-terrorism police have raided the offices of an aid agency on the border with Syria, in what local media described as an operation in six cities against individuals suspected of having links to al-Qaeda.
The Humanitarian Relief Foundation (IHH) said police on Tuesday raided its offices in the southern Turkish city of Kilis, which borders Syria, and detained one person.
"We see this as part of a dirty plot," said the charity's vice president, Huseyin Oruc, noting police had not given a reason for the raid. The IHH denied any ties to al-Qaeda.
