Pakistan and Iran on Friday denied allegations that Islamabad helped Tehran develop its nuclear programme and said the reports appearing in the US media are baseless and motivated.

"We reject the reports about nuclear co-operation as totally baseless and inaccurate," Pakistan Foreign Minister Khurshid Mehmood Kasuri said in a joint news conference with visiting Iranian Foreign Minister Kamal Karazi.

Karazi arrived in Islamabad on a day's visit on Friday and held talks with President Pervez Musharraf, Prime Minister Mir Zafarullah Khan Jamali and Kasuri on trade co-operation between the two countries.

Dismissing reports appearing in British and US media stating that Pakistan supplied centerfuges to Iran to develop its nuclear programme, Kasuri said: "Pakistan has never supplied in any manner, whatsoever, any assistance for Iran's nuclear programme."

Karazi said Iran's nuclear programme is for peaceful purposes and Tehran has no plan to develop nuclear weapons.

On the contrary, he said, Iran is desirous of having nuclear free zones in the middle-east and the Indian sub-continent.

He said Iranian nuclear programme is indigenous and developed with technology available in Iran.
