KABUL, Dec. 25 (Xinhua) -- At least four people were killed and one other wounded after a suicide bomb explosion rocked near an intelligence agency office in central neighborhood of Kabul on Monday morning, a health official said.

"Three dead and one injured were admitted to hospitals after this morning's bomb attack," Ismahil Kawusi, a spokesman of Public Health Ministry, told local media, adding the attacker also died on the spot.

"The blast came at around 07:20 local time in Shash Darak locality after the attacker detonated his explosive vest near a National Directorate of Security (NDS) sub-office. The whole place has now been sealed off," an eyewitness told Xinhua.

The NDS is the country's primary intelligence agency.

Sirens could be heard after the blast in the area where several foreign embassies, the NATO-led coalition forces' headquarters, and scores of apartment buildings are located.

No group has claimed responsibility for the attack yet.
