TEHRAN, Iran (AP) — A top Iranian lawmaker has rejected the possibility of Iran shipping uranium abroad for further enrichment.

The call by prominent conservative lawmaker Alaeddin Boroujerdi intensifies pressures on the government to reject a U.N.-backed plan to allay international concerns over Iran's nuclear program.

The semiofficial ISNA news agency quoted Boroujerdi Saturday as saying that Iran won't ship its low enriched uranium abroad in a single batch or in several shipments under any circumstances.

Earlier, Iran had indicated that it might agree to send only "part" of its stockpile in several shipments.

The lawmaker said Iran itself should be doing the necessary enriching.

Enriching uranium can turn it into nuclear fuel, or if done further, material for a weapon.
