ISTANBUL — ******* ****** arrested two people Wednesday after a hand ******* was hurled and ***** were ***** at officers guarding Istanbul’s Dolmabahce Palace, an Ottoman-era palace that is a major tourist attraction, the Istanbul governor’s office said. One ****** officer was slightly *******, according to the country’s state-run news agency.

Later Wednesday, at least eight ******* soldiers were ****** by a roadside **** detonated by Kurdish ****** in Turkey’s mainly Kurdish southeast region, the military said.

****** apprehended two people in an area close to the palace and seized two hand-grenades, an automatic rifle, a hand *** and a large amount of ammunition, a statement from the Istanbul governor’s office said. It did not identify the suspects or give a motive for the ******.

However, the state-run Anadolu Agency said the two assailants are members of the outlawed leftist group the Revolutionary People’s Liberation Army-Front, or DHKP-C. It did not cite a source for the report.

The DHKP-C claimed responsibility for an ****** earlier this month in which two female assailants opened **** at the U.S. Consulate in Istanbul. No one was hurt in the ****** but one of the assailants was shot by ****** and hospitalized.

The ******* come amid a sharp rise in ******** between Turkey’s security forces and the Kurdish ******, and as Turkey has been conducting operations against the Islamic State group and others. Turkey last month rounded up more than 1,000 people linked to IS, the Kurdish ****** and the DHKP-C, after a ******* **** ****** blamed on IS ****** 32 people. ******* warplanes, meanwhile, have raided PKK targets in Iraq and in southeast Turkey in tandem with airstrikes against Islamic State militants in Syria.

Close to 100 people, most of them ****** and soldiers, have been ****** since July in the renewed ******** between the security forces and the Kurdistan Workers’ Party, or PKK, according to a count by The Associated Press.

An IS propaganda video released this week called Turkey’s president, Recep Tayyip Erdogan, a traitor for allowing the U.S. to use air bases for strikes against the group, and urged all Muslims in Turkey to join the IS in its fight against “crusaders, atheists and tyrants” in the country.

The ****** officers who were attacked were standing guard at an area far from the entrance used by visitors to the 19th century Dolmabahce palace.

Margarita Paban, a visitor from Poland, said she heard a “boom” and three or four *** ***** as she emerged from the tramway with her family.

She said they had no plans to cut their visit short.

“We have more sights to see,” she said. “We haven’t seen the Grand Bazaar or the Asian side yet.”

The prime minister has an office inside the palace, situated on the shores of the Bosphorus strait, but was in the capital Ankara at the time of the ******.
