Story highlights Roadside bomb kills 8 soldiers in southeastern Turkey's Siirt province

In Istanbul, 2 carrying automatic weapons arrested follow gunfire reported near police station

No injuries or deaths immediately reported in Istanbul

Istanbul, Turkey (CNN) Eight soldiers were killed Wednesday afternoon by a roadside bomb attack blamed on the Kurdistan Workers' Party, or the PKK, the Turkish military said.

The soldiers were traveling in an armored vehicle in southeastern Turkey's Siirt province when a remote-controlled bomb exploded, Turkey's semiofficial Anadolu Agency reported.

Also Wednesday, two gunmen were arrested near Istanbul's Dolmabahce Palace, Turkey's Dogan News Agency reported after gunfire erupted close to a police post at the palace.

No injuries or deaths were immediately reported in that incident. The Istanbul governorate said the two suspects were carrying automatic weapons and hand grenades.

Anadolu said the suspects are members of the far-left Revolutionary People's Liberation Party-Front or DHKP-C. Last week, Anadolu reported two female members of DHKP-C were responsible for the shooting at the U.S. Consulate in Istanbul on August 10. The group claimed responsibility for a 2013 suicide bombing at U.S. Embassy in Ankara.
