Three rockets have fallen in the Green Zone near the US embassy in Baghdad, an Iraqi security source reported.
"Three missiles landed in the area close to the US embassy in the 'green zone' in Baghdad, air raid sirens are heard from the embassy", the source said.
Reuters reported earlier of blast heard in the city, but added that the cause was unknown.
Supposed videos from the scene with sirens sounding have been shared on social media.

The Iraqi security source later confirmed there were no casualties as a result of the shelling.
"There are no casualties resulting from the landing of missiles next to the US embassy", the source said.
The Green Zone is in central Baghdad, where government buildings and diplomatic facilities are located. It is not the first time the area has come under attack recently. Earlier on 8 January, another two rockets fell in the centre of Baghdad.
On 6 January, heavy shelling targeted central Baghdad, which the Iraqi military identified as Soviet-made katyusha-type projectiles.
