Explosions in the Afghan capital Kabul have killed at least 26 people, including nine journalists who had arrived to report on an initial blast and were apparently targeted by a suicide bomber.
The attacks on Monday, a week after 60 people were killed as they waited at a voter registration centre in the city, underlined mounting insecurity despite repeated government pledges to tighten defences.
Hours after the attack in Kabul, a suicide bomber in a vehicle attacked a foreign military convoy in the southern province of Kandahar, killing 11 children studying in a nearby religious school, police said.
"These attacks caused untold human suffering to Afghan families," said Tadamichi Yamamoto, the top UN official in Afghanistan.
"I am furthermore outraged by the attack which appears to have deliberately targeted journalists," he said.
US Secretary of State Mike Pompeo strongly condemned the "senseless and barbaric" bombings in Kabul.
"Despite today's attack, the vibrant media landscape that has developed in Afghanistan will endure," he said in a statement.
The attacks in rapid succession were a grim reminder of the strength of both the Taliban and Islamic State's emerging Afghanistan branch to wreak violence despite stepped-up US air attacks under Trump's new policy for the 16-year-old war.
Islamic State claimed responsibility for the two blasts in the capital, which killed at least 26 people, including four police, and wounded 49 seriously, police said.
The Afghan Journalists Safety Committee (AFJSC) said nine journalists were killed in Kabul, the worst toll for media workers in a single attack in the country.
Najib Danish, a spokesman for the interior ministry, said a suicide bomber appeared to have posed as a media worker and blew himself up where reporters and rescue workers had gathered.
"We know that a suicide bomber pretended to be a reporter. He showed his press card and stood among journalists before blowing himself up," Danish told Reuters.
In a separate incident, Ahmad Shah, a journalist who worked for a local language service of the BBC and for Reuters, was shot dead in the eastern province of Khost, officials said.
His death was confirmed by the BBC but there was no indication of any connection with the Kabul attack, the most serious on the Afghan media since 2016, when seven workers for Tolo News were killed in an attack claimed by the Taliban.
