Three women working for a TV station in Afghanistan’s Jalalabad city were shot dead.
The women, reportedly between 18-20 were killed in two separate but co-ordinated attacks. A fourth was critically hurt.
Police say they arrested the lead gunman, linking him to the Taliban. The group deny any involvement.
A wave of killings has rocked the country with journalists, activists and other political figures being targeted.
The three women killed had recently finished high school and worked in the dubbing department of the privately owned Enikas TV station, said its head, Zalmai Latifi.
According to the Associated Press, Mursal Wahidi was attacked by gunmen as she was walking home. The two others – who were identified only as Shahnaz and Sadia – were killed in a separate incident, also while returning home.
“They are all dead. They were going home from the office on foot when they were shot,” Mr Latifi told AFP news agency.
The injured woman was taken to hospital where she was fighting for her life, a spokesperson was quoted by Reuters as saying.
Police are still looking for other attackers after they arrested the main suspect, Nangarhar police chief Juma Gul Hemat said, according to AFP.
“We arrested him as he was trying to escape,” said Mr Hemat. “He has admitted that he carried out the attack. He is a Taliban member.”
Enikas TV station says of 10 women it employed, four have now been killed including a presenter, Malalai Maiwand, who was gunned down in December.
Last month, two women Supreme Court judges were shot dead in the capital, Kabul.
