At least 24 people including six Afghan security forces were killed in twin bombings near the Presidential Administrative Office in Kabul on Monday, officials said.
"At least 91 others were wounded," said Wahidullah Majroh, a spokesman for the Afghan ministry of health, adding that some are in critical condition.
Security forces rushed to the scene after an initial explosion at the end of office hours. This was followed by another blast when a suicide bomber blew himself up among the crowd that had gathered to assist the injured.
Among those killed was General Abdul Raziq, a senior Afghan army official and the chief of police for district two of Kabul city.
"Gen. Raziq succumbed to his wounds in a hospital," said General Mohammad Radmanish, a spokesman for the Afghan Ministry of Defence.
"He was assisting with the wounded from the initial blast when the second suicide bombing occurred," Radmanish added.
The incident occurred in one of the most crowded areas of the capital where the Presidential Administrative Office, Ministry of Defence and district police headquarters are located, all within close proximity of each other.
The Taliban claimed responsibility for the attack, adding that it had killed tens of soldiers and officers in its recent effort to take chunks out of the security elite in Kabul.
President Ashraf Ghani condemned the attack in a statement saying "terrorst groups attempt to reach their ominous goals by spreading fear."
Sixteen people were killed late last month and 39 others wounded in another Taliban attack on the American University of Afghanistan.
In April, 64 people were killed and more than 300 others were wounded after the Taliban attacked an organization providing security for the Afghan elite.
