MPs have been told to evacuate the Turkish parliament building in Ankara over an unspecified security threat, according to an opposition politician.

The Cumhurriyet newspaper quoted the Peoples' Democracy Party member Ziya Pir as saying: "We have been informed of an attack. The Meclis is being evacuated."

The parliament building was among the public assets bombed by plotters during the coup attempt on the night of July 16.

A dramatic video captured by one MP showed the moment the first bomb hit while politicians were still in session, crashing through the roof into a courtyard.

Meanwhile, an unknown assailant has shot the deputy mayor of Istanbul's Sisli district in the head, Turkish broadcaster NTV reported.

It was not immediately clear whether the incident was linked to Friday's abortive military coup in which more than 200 people were killed. Turkey remains in a state of high tension, though the government says it has the situation fully under control.

NTV reported that the assailant had entered the office of deputy mayor Cemil Candas and then gun shots were heard. Turkey's main opposition Republican People's Party (CHP) runs the prosperous Sisli district. Along with other opposition parties the CHP has condemned the attempted coup.

More than 300 people died and some 1,500 people were injured in the clashes, which ended when soldiers involved in the coup gave up their weapons and handed themselves in.

Turkey's state-run news agency says a total of 103 generals and admirals have been detained for questioning across Turkey over the failed coup.

Anadolu Agency says Monday that 41 of them have been ordered jailed pending trial so far.

Earlier, the agency said prosecutors in Ankara were questioning 27 generals and admirals, including former Air Force commander Gen. Akin Ozturk, who has been described as the ringleader of the foiled uprising.
