CNN-Turk television reported some police officers and parliament workers were hurt in the bomb attack.
A resident living not far from the area told the AP he heard a massive explosion that shook buildings and saw a column of smoke but could not confirm if it was coming from parliament itself.
The person, who spoke on condition of anonymity for security reasons, also said fighter jets were flying low in the area.
Turkey’s armed forces said it “fully seized control” of the country Friday and its president responded by calling on Turks to take to the streets in a show of support for the government.
A loud explosion was heard in the capital, Ankara, fighter jets buzzed overhead, gunfire erupted outside military headquarters and vehicles blocked two major bridges in Istanbul.
Turkish news agency Dogan has reported that soldiers have opened fired on people trying to cross Istanbul’s Bosporus bridge in protest of the attempted coup, and some have been wounded.
TV footage showed people running for cover as shots rang out. Earlier, a statement attributed to the military said that Turkish armed forces have “fully seized control” of the country.
President Recep Tayyip Erdogan then called on citizens to take to the streets in a show of support for the government.
