DIYARBAKIR, Turkey (Reuters) - Turkish tanks on Tuesday pounded Kurdistan Workers' Party (PKK) targets in Cizre, a southeastern town at the heart of a large-scale military operation that the army said has killed 127 Kurdish militants in a week.
Black smoke rose from buildings in the town after shelling from hilltops, Reuters TV footage showed, and the pro-Kurdish Peoples' Democratic Party (HDP) said at least 23 civilians had been killed in the violence.
A prosecutor opened an investigation against HDP leader Selahattin Demirtas, two other HDP lawmakers and two senior Kurdish politicians. They are accused of violating anti-terrorism laws and encouraging criminal activity at a press conference last week where Demirtas urged Kurdish citizens to "resist" the operations.
Turkish lawmakers cannot be prosecuted unless parliament first strips them of their immunity.
Clashes have forced tens of thousands of people to leave their homes in Sur, a historic district of the region's largest city Diyarbakir, which has been under curfew for three weeks, CNN Turk said, citing a report prepared by the main opposition Republican Peoples Party (CHP).
Turkish security forces launched a new offensive in the mainly Kurdish region last week, backed by tanks and thousands of troops, after President Tayyip Erdogan pledged to root out militants.
The towns of Cizre and Silopi, bordering Iraq and Syria, have been the focus of the campaign. Images on state media from Sur have shown Turkish troops patrolling rubble-strewn streets among buildings riddled with bullet holes.
A two-year ceasefire between the PKK and Ankara fell apart in July, shattering peace talks and reviving a conflict that has afflicted Turkey's mainly Kurdish southeast for three decades, killing more than 40,000 people.
The PKK, which launched its insurgency in 1984, is designated as a terrorist group by Turkey, the United States and the European Union.
Traditionally focused on the countryside, the PKK has shifted to southeastern towns, setting up barricades and digging trenches to keep security forces away.
Demirtas said the campaign was targeting locals who were presented as "terrorists".
"We stand by our people who resist the tanks and shelling," he said before leaving for Moscow on a visit criticised by Prime Minister Ahmet Davutoglu.
Turkey and Russia have been at odds since Ankara downed a Russian jet involved in operations against rebels in Syria last month, saying it had violated Turkish air space.
"TARGETS FOR BULLETS"
Many towns are under curfew and electricity has been cut in many Silopi districts as transformers have been damaged. Food and water was running scarce in some Diyarbakir districts, while shopkeepers kept shutters closed in protest at the security operations, residents said.
Ferhat Encu, an HDP lawmaker for Sirnak, said on Twitter that the bodies of those killed in clashes in Silopi were being kept in houses due to the curfew.
The Kurdish Islamist party Huda-Par, usually sympathetic to the ruling AK Party, said security forces were taking positions inside civilian houses, including those of two party members, against the residents' will, therefore making them a target.
"Due to the curfew, our members and their families cannot leave their house and move to a safer place and therefore have become targets for bullets," a party statement said. It added that entering people's homes by force, whether by the state or the PKK, was trespassing and "unacceptable".
On Tuesday, a Turkish soldier was killed in Bitlis, the army said, during an operation that killed two PKK militants.
