Pakistani soldiers fence the Afghan border in Chaman on January 4 (epa)
January 8, 2007 -- The UN's deputy special representative in Afghanistan, Chris Alexander, has called on the Afghan and Pakistani governments to stop their "war of words."
Kabul and Islamabad have been at odds over Afghan accusations that the Taliban use Pakistan's territory to attack Afghan and international forces in the country.
Islamabad has consistently rejected the accusations.
Speaking in Kabul today, Alexander also called on Pakistan to drop its plan to mine parts of the border to prevent militants from crossing into Afghanistan.
Alexander said land mines represent a "very serious threat" to the security of local populations.
Afghan President Hamid Karzai has also rejected the plan.
The UN representative also expressed his concern about support in Pakistan for the Taliban movement and urged Islamabad to take more action against Taliban leaders.
