The Taliban accused the Afghan government and South Korean negotiators of failing to act in good faith after they rejected a list demanding eight named rebel prisoners be freed.
“Since Kabul‘s administration did not listen to our demand and did not free our prisoners, the Taliban shot dead a male Korean hostage,” a Taliban spokesman said.
“If the administration of Kabul is not ready to release our hostages, then by 1 am (local time) the rest of the hostages will be killed,” he said. “That time is the last deadline.”
He said the Korean hostage had been killed in a desert area in the Qarabagh district of Ghazni close to where the 23 Korean church volunteers, 18 women and five men, were abducted on the main road south from Kabul last week.
Anxious family members of the Korean hostages gathered at the offices of a non-governmental agency in Seoul to follow developments on television. Sounds of crying emerged when news came out that one of the hostages had been killed.
Around 1,000 people gathered in suburban Seoul around Saemmul church, which sent the volunteers to Afghanistan, to pray for their safe return, broadcaster YTN reported.
The Taliban meanwhile freed a German journalist, the third German to be kidnapped in a week in war-torn Afghanistan, and his Afghan translator hours after abducting them in the east of the country, officials said.
The fresh hostage crisis for Germany was defused after a few hours in eastern Afghanistan‘s Kunar province bordering Pakistan.
The pair were abducted from a house in the far-off district of Watapour where a NATO-led air strike killed several Afghan civilians two weeks ago, Shalizai Didar, the provincial governor, said.
“They were both freed with the mediation of tribal elders and other influential people. They are safe and sound,” Didar told AFP.
The Taliban had earlier claimed responsibility for kidnapping the German journalist.
The two other Germans were kidnapped last week in the southern province of Wardak.
The bullet-riddled body of one was dumped by a road on Sunday while the Taliban said the other was very sick and slipping in and out of consciousness due to diabetes.
