A bomb exploded at an office of Afghanistan's main news agency on Thursday, wounding two people and causing damage in the latest attack on the country's media.

The blast that took place at about 8pm damaged tables, chairs, computers, video cameras and other equipment in the office situated in the Ghalji Plaza in Jalalabad, Pajhwok cameraman, Babrak Amirzada, said.

Pajhwok correspondent in Nangarhar, Zeerak Fahim, said two guests of a reporter with the Voice of America Radio station situated next to the Pajhwok bureau were wounded in the blast.

"We have received threats and letters from insurgents from time to time when they were not happy about our stories and coverage of incidents," Karokhil told.

"I urge the government to do more to protect journalists and call on all parties in the conflict not to create hurdles," he added.

Ahmad Zia Abdulzai, a spokesman for the province's governor, said police were investigating and it was not clear why the agency had been attacked.

No group claimed responsibility for the blast at the office of the Pajhwok news agency in the eastern province of Nangarhar but its editor-in-chief, Danish Karokhil, said militants had issued threats in the past.
