Bulgaria as a NATO member will join a possible strike on Iran should the Alliance decide to launch such an attack, Bulgarian Defence Minister Vesselin Bliznakov said.

Talking to private bTV channel Bliznakov said that the US might attack Iran in an aim to stop it from developing nuclear weapons. In his words this might happen should the situation become really complicated.

Bulgaria boasts really good relations with the countries from the Arab world, but there are not enough guarantees that Iran is not developing a nuclear weapon, Vliznakov underlined.

There are reports that the US military are drawing up a plan for attack on Iran in an aim to stop it from developing nuclear weapons. The plan is a military back-up in case diplomatic efforts fail, a UK newspaper reported.

Meanwhile, on Monday UN diplomats said that Iran has restarted uranium enrichment work. They said it had begun feeding uranium gas into centrifuges - a first step in a process that can produce fuel for nuclear reactors or bomb material.

Tehran had warned it would resume enrichment after the UN nuclear watchdog decided to report it to the UN Security Council nine days ago.
