Iran saw missile test, US says

WASHINGTON -- The United States said yesterday Iran had attended North Korean missile tests this month, increasing US concern about ties between two countries Washington accuses of having secret nuclear weapons programs.

No comment on the US charge was immediately available from Iran, which earlier accused Washington of trying to obstruct talks to end a standoff over Tehran's nuclear program.

The accusations were traded as the UN Security Council wrangled over a resolution to make legally binding demands Iran halt uranium enrichment, a process that can produce fuel for power stations or bomb material. Iran again rejected international calls for it to scrap nuclear fuel production.

US Assistant Secretary of State Chris Hill said one or more Iranian representatives witnessed July 4 missile tests in North Korea .
