While Afghanistan is just three weeks away from the landmark parliamentary elections the United Nations' country office expressed its concerns over the security situation in the war-torn nation Thursday.

"Security remains a paramount concern for the elections. It is very clearly difficult for any government to deliver the services it needs in an environment where security is a problem," Adrian Edwards of UN Assistance Mission in Afghanistan (UNAMA) told journalists.

He made this comment amid increasing militancy in the rugged southern terrain and militants' threat to disrupt the electoral process in the post-Taliban nation.

"This is a massive elections, this is an historic elections, so security is a concern," he emphasized.

Meantime, the special envoy of UN secretary General to Afghanistan Jean Arnault has been in New York this week to brief the UN Security Council on security situation in the post-conflict nation.

Nevertheless the security threat, the UN-sponsored Joint Electoral Management Body (JEMB) is confident the key elections will be held in a peaceful environment but amid tight security as per schedule next month.

Some 30,000-strong US-dominated foreign troops and NATO-led International Security Assistance Force (ISAF) in conjunction with around 50,000 Afghan army and police have been working to ensure security for the historic legislative elections salted for September 18.
