A Taliban suicide bomber targeted a minibus carrying journalists working for a private Afghan television channel on Wednesday, killing seven employees in an area close to the Russian embassy in the Afghan capital Kabul, police said.
"A suicide bomber driving a (Toyota) Corolla car attacked a van which belonged to Kaboora Production in this area. So far at least seven people including two women were martyred and 25 other people were wounded," said Kabul police chief Abdul Rahman Rahimi.
He did not specify how many of the van's passengers were among the casualties.
The Ministry of Public Health confirmed that at least 20 had been wounded. The Russian embassy said none of its staff were hurt in the attack.
"Police are working to identify the victims of today's attack, but there was no military convey (in the area), they were all civilians," Sediqqi said.
Since the start of the new year, Kabul has seen at least six bomb attacks. A rocket landed near the Italian embassy in Kabul on Sunday, wounding two security guards.
The attacks have coincided with renewed efforts to revive the peace process with the Taliban, efforts broke down in July.
"If they do not stop their evil activities this will not be the last attack on them," Zabihullah Mujahid, a Taliban spokesman, said in an emailed statement.
Representatives from Afghanistan, Pakistan, China and the United States, who met in Kabul this week to lay the ground for a negotiated end to 15 years of war, urged the Taliban to join the peace talks.
