The threat after the July 15 coup attempt is not over, Turkey's presidential spokesman said on Saturday.

Speaking in a live broadcast on Turkey's NTV television channel, İbrahim Kalın said "brutal murderers" were capable of doing anything, like carrying out suicide attacks and fermenting demonstrations to cause chaos.

Asked if the state of emergency could be extended at the end of three months, Kalın said it might be.

Kalın also said Turkey's detention period, which was increased to 30 days, was similar to a 28-day detention period in the U.K.

"The French government also declared a state of emergency for three months after the deadly attacks in Paris," Kalın added.

Criticizing some foreign comments about the coup attempt, Kalın said the Turkish government, opposition parties and Turkish people had confronted the plot.

Recalling claims suggesting 'Turkish President Erdoğan will suppress the opposition in Turkey taking advantage of the failed coup', Kalın said: "If you say so, then I say: 'You are trying to attack Turkey, taking advantage of this failed coup'."

Kalın said some groups in Turkey and abroad, who had been nurturing enmity towards President Recep Tayyip Erdoğan under the name of politics and journalism, made claims that the failed coup by the FETÖ terrorist organization was staged.

"This is no different to claiming the 9/11 attacks were orchestrated by the United States or the recent Paris attacks and Nice attack were orchestrated by the French government," Kalın said.

"You cannot dare to say these conspiracies about America, France and Belgium; however, if it comes to Turkey you accept these nonsensical conspiracies as journalism and political analyses. It is disrespectful to the democratic reflex of the people."

Kalın also stated that a number of countries expressed their support for Turkey and wanted to send representatives in a show of support.
