Iran first began experimenting with nuclear energy in the 1950s when it received US assistance to build the country's first nuclear reactor.

At the time, the Eisenhower administration in Washington saw Tehran as a vital ally and pursued a co-operative programme to push US scientific and commercial involvement in Iranian civilian nuclear industries.

In the 1970s, the Iranian government sought - and received - assistance from other western nations such as Germany and France.

Despite US intelligence warnings that Iran could have nuclear weaponisation ambitions, Western assistance continued.

However, the overthrow of the Shah in 1979 and the rise to power of Islamist leaders like Ayatollah Khomeini brought the co-operation to an end.

As the war with Iraq raged until 1988, Iran resumed its interest in a national nuclear programme.

Following the Gulf War in 1991 and the UN sanctions slapped on Iraq for its alleged weaponisation programme, Iran began to dedicate funds to speed up its research and development of nuclear power.

In 1995, Russia signed several nuclear deals with Iran; development of the nuclear programme continued relatively unhindered until an opposition group revealed that Tehran had overcome several technological obstacles in securing nuclear power.

Below are key dates since 2002 when the West and Iran clashed over its disputed nuclear programme.
