Iran today confirmed that it has fully developed solid fuel technology for producing missiles. Associated Press quoted Defence Minister Ali Shamkhani as saying the Islamic Republic has "fully achieved proficiency" in solid fuel technology in producing missiles. Solid fuel makes missiles more durable and accurate. Iran produces nuclear-capable missiles which can reach targets up to around 2,000 kilometres away from their launch sites. Also today, Iran's outgoing President Mohammad Khatami said Iran will resume some sensitive nuclear work regardless of what proposals the European Union makes He added: "They (Europeans) accepted to present their comprehensive plan by the end of July or in the beginning of August. We had presented our plan and we were waiting for them to offer their plan. We told them then that if the freeze of (uranium) enrichment was included in the plan, it would be rejected." Iran suspended some of its nuclear activities in November as part of negotiations with the EU on providing guarantees that its nuclear program is exclusively civil in return for a package of incentives. The United States says that Iran is using its nuclear facilities to covertly develop a nuclear arsenal. Iran denies it.
