Iran Pardons, Releases Jailed Swedes
Iran has pardoned two Swedish nationals jailed for photographing military installations last year and will release them today.
Foreign Ministry spokesman Mohammad Ali Hosseini made the announcement in a statement issued today.
The two men were arrested in March 2006 for taking pictures of military installations on Iran's southern island of Qeshm and sentenced to two years in prison.
Hosseini said the two were released for humanitarian reasons and following the requests of their parents and Swedish politicians.
Iran Deplores West's 'Bullying Methods'
President Mahmud Ahmadinejad today vowed that Iran would resist "to the end" the standoff over the country's nuclear drive.
In a televised speech in the southern city of Shiraz, Ahmadinejad warned world powers to give up "bullying methods" and not to "misuse" the UN Security Council.
"You should know that by misusing the international organizations that you have created and set the rules for, you will not be able to [undermine] the will of the Iranian nation," Ahmadinejad said.
The comment comes a week after Ahmadinejad announced that Iran was capable of producing nuclear fuel on an industrial scale through enrichment.
The council had imposed two sets of sanctions on Iran over its refusal to suspend uranium enrichment. Western nations suspect Iran's nuclear program is aimed at producing atomic weapons. Tehran denies this.
