Security officials would not immediately comment on the sweep, which reportedly targeted the region of Tebessa, 400 miles east of the capital, Algiers.
Anti-terrorist forces launched an operation Thursday based on information from 11 suspects arrested last week and believed tied to a suicide bombing that targeted President Abdelaziz Bouteflika's convoy Sept. 6, the daily newspaper Liberte reported.
That bombing left at least 22 dead, and was claimed by a group called al-Qaida in Islamic North Africa.
For about a month, about 20 fighters believed involved with the al-Qaida affiliate have been hiding out in the forests in the Tebessa region, Liberte said.
The report said the sweep killed 22 Islamic militants. Seven soldiers were killed when a homemade bomb exploded, it said.
Algeria has seen a revival of violence in recent months after a period of relative quiet following an insurgency that ripped the country apart in the 1990s and has left as many as 200,000 dead.
Isolated hard-line Islamic groups have now aligned with al-Qaida to recover ground, delivering a string of setbacks this year to government efforts to bring calm and prosperity to this oil- and gas-rich country.
In recent months, the army repeatedly has bombed and burned forests where rebels are believed to be hiding.
