At least 20 Afghanistan policemen have been killed after being ambushed by the Taliban.
The officers were targeted in the Shah Joi district of Zabul province.
Provincial governor Bismullah Afghanmal said the Taliban had attacked police in the areas of Chino and Ghulam Rabat, and that he feared there could be more deaths.
"The report we have right now indicates that 20 policemen are martyred and 10 others are wounded. The number may increase," he said.
He added dozens of Taliban, who have been waging a 16-year-long insurgency against the Western-backed government in Kabul, were also wounded and killed.
The militant group admitted carrying out the attacks which it said were part of Operation Mansouri - a spring offensive it announced at the end of April.
Meanwhile, a German aid worker and Afghan guard were killed, and a Finnish woman believed kidnapped, when gunmen stormed an international guest house in the capital Kabul.
The foreign ministry in Stockholm urged those who have reportedly taken her to release her.
"At the moment, the identity of the kidnappers in not known. Finland urges immediate release of the kidnapped person," the Finnish ministry said.
The guest house is run by Swedish relief organisation, Operation Mercy.
No group has yet claimed responsibility for that attack - which is the latest in a series of assaults on aid workers in the country.
More than 100 Afghan soldiers were killed last month as Taliban fighters attacked an army base during Friday prayers.
More than 8,000 US soldiers remain in the country. It's not clear if President Trump will send more, despite the end of combat operations three years ago.
