KABUL, Afghanistan (AP) — A suicide bomber in a truck blew himself up at an intelligence headquarters in eastern Afghanistan on Saturday, killing at least two people and setting off an intense firefight with security forces, officials said.

After the bombing outside the headquarters of the National Directorate of Security in Jalalabad, militants battled with security forces for an hour before authorities were able to put down the attack, said Ahmad Zia Abdulzai, a spokesman for the Nangarhar governor.
