A rare suicide attack hit a commercial street in central Baghdad on Thursday morning, state television reported, adding that there were dead and wounded without giving any figures.
According to three police officials, seven people have been killed in the attack so far and more than 25 others wounded.
The officials spoke on condition of anonymity in line with regulations.
They also said the death toll from the attack inside a crowded market in Baghdads Tayaran square could rise as some wounded people were in a critical condition.
Iraqi state television reported it was a suicide bombing.
After years of deadly sectarian violence, suicide bombings have become relatively rare in the capital. The last such attack took place in June 2019 and left several people dead.
The attack was not immediately claimed but suicide attacks have been used by armed groups, most recently the Islamic State organisation.
Iraq declared IS defeated at the end of 2017 after a fierce three-year campaign.
But the groups sleeper cells have continued to operate in desert and mountain areas, typically targeting security forces or state infrastructure with low casualty attacks.
More soon.
