Ambulances and fire fighters rushed to Ankara’s central Cankaya neighbourhood where many other institutions and embassies are also located.

Contrary to early reports in the Turkish press, the explosion is understood not to have been caused by a suicide bomber.

“It was not a suicide bomber or car bomb. Someone left a package or threw a package,” the source said.

An Associated Press journalist reported seeing a body in the street at a side entrance.

It was not immediately clear what the cause of the blast was.

He was driving about 400 metres away from the US embassy when the reported blast happened.

Two more people have reportedly been injured.

A  witness on the ground has contradicted earlier Turkish media reports that the blast was caused by a suicide bomber. One source at the nearby British Embassy told the Daily Telegraph that the explosion was caused by a bomb.

“It was not a suicide bomber or car bomb. Someone left a package or threw a package,” the source said.

However, witnesses told CNN’s Turkish service that a bomber was seen appraching the building and later entereed a gate at the fortified compound.

Initial reports say the blast occurred near the gates of the visa section of the embassy compound. Security has been tightened around the embassy as there are fears that a second bomb could be detonated.

Dozens of ambulances and firefighters were dispatched to the scene.

Turkish TV footage showed smoke rising, with damage to the side entrance of the US embassy.
