Two policemen and six civilians were wounded in the attack, which targeted a police vehicle in the Kurdish-majority province of Diyarbakir.
Anadolu said the Kurdistan Workers' Party (PKK) was to blame for the attack, which damaged buildings in Dicle district.
Hundreds of members of the Turkish security forces have been killed in PKK attacks since a truce between the government and the militants collapsed a year ago.
But the government has vowed no let-up in a relentless campaign to wipe the militants from urban centres of Kurdish-dominated southeastern Turkey.
Since then the group has narrowed its demands to greater autonomy and cultural rights.
