KABUL, Aug. 29 (Xinhuanet) -- The United Nations has suspended its field activities in Rodad district of eastern Nangarhar province in Afghanistan as one of its vehicles hit an explosive device Saturday, the spokesman of UN Assistance Mission in Afghanistan (UNAMA) said.

    "The UN has suspended road mission to Rodad district temporarily after one of the vehicles of the Joint Electoral Management Body (JEMB) was hit by improvised explosive device late yesterday morning," Manoel de Almeida e Silva said at a news briefing here Sunday.

    The spokesman said that preliminary reports suggest that the improvised explosive device "had a remote control system and it could have targeted the JEMB vehicle."

    "No one was hurt, however, the vehicle did have some minor damages," the spokesman added.

    It was the latest attack on the election workers but no group or individual has claimed responsibility for that.

    Due to efforts of the UN-sponsored JEMB, over 10.5 million Afghans have registered to participate in the Oct. 9 presidential elections as well as parliamentary polls in next April.

    Earlier, remnants of the former Taliban whose regime was unseated under a US-led military operation in late 2001 have on many occasions accepted responsibility for such attacks.

    Twelve election workers have been killed and over 30 others injured in the interval of the beginning of electoral process in late last December and the closure of voter registration sites in the nation on Aug. 15.

    "We suspended road movement in Rodad until we have a fair understanding of what actually happened," the spokesman said. Enditem
