Berlin, April 2, IRNA -- The Islamic Republic of Iran has pledged 154 million US dollars over the next three years towards Afghanistan's political and economic reconstruction program, an Afghan Finance Ministry press release said here Friday.

Donor nations at the third Afghanistan conference which concluded its work on Thursday pledged 8.2 billion dollars for the next three years towards the rebuilding of the war-ravaged country.

The new financial aid falls well short of the 27.5 billion dollars which Afghan President Hamid Karzai had requested for the next seven years.

Karzai earlier urged continued international political and economic support for his country, warning that warlords, drugs and poverty still pose grave dangers to Afghanistan's rebuilding process. He called on the international community not to allow his country to "slip back into a haven for drugs and terrorism."

More than 60 delegations comprising 700 conference participants from over 40 countries attended the Afghan summit in Berlin amid tight security.
