Turkish daily Sozcu said that the embassy had been evacuated after authorities were informed of a planned suicide bomb attack on the building.
However a Reuters TV cameraman at the scene said visitors to the embassy reported that operations were continuing normally despite heightened security in the area.
Police carried out searches on vehicles and the road on which the embassy is located was briefly closed to traffic, he said, adding that it was later reopened.
Iran’s foreign ministry denied that there was a bomb threat against the embassy and denied that the building had been evacuated, state TV reported.
