Two suicide car bombings in eastern Afghanistan on Sunday killed two intelligence agents and a police officer, officials said.
In the first attack, a suicide bomber rammed an explosives-laden car into a spy agency facility in the eastern town of Jalalabad, 150 kilometres (90 miles) east of Kabul.
It was followed by a similar attack on a police base in Logar, 70 kilometres south of the capital, officials said.
He said the attacker rammed his vehicle into the gate of the walled compound and detonated his bombs.
Police in Logar said the attack there hit a police base along the highway leading to Kabul and killed one police officer.
Taliban spokesman Zabihullah Mujahed claimed responsibility for the Logar bombing. There was no immediate claim for the Jalalabad attack.
The Taliban are the main insurgent group behind suicide bombings in Afghanistan in a long-running insurgency aimed at toppling the Western-backed government in Kabul.
