Opposition parties in Liberia on Saturday said they were pulling out of the elections, claiming fraud, as vote-counting put incumbent President Ellen Johnson Sirleaf in the lead.

"We are pulling out of the process because it is not democratic and there is a lot of fraud," an opposition source said in the wake of the October 11 elections which also included parliamentary and senatorial polls.

Liberian President Ellen Johnson Sirleaf, Liberian "peace warrior" Leymah Gbowee and Yemen's Arab Spring activist Tawakkul Karman on Friday won the Nobel Peace Prize, the jury said.

The three prizewinners share the 2011 award "for their non-violent struggle for the safety of women and for women's rights to full participation in peace-building work," Norwegian Nobel Committee president Thorbjoern Jagland said in his announcement.

Seven men, including two Lebanese citizens, were charged with selling drugs and weapons in an effort to help the Taliban fight U.S. troops overseas.

Posing as representatives of the Taliban, cooperating witnesses for the Drug Enforcement Administration approached the men in Ghana last June, asking to set up a drug relationship, prosecutors said. First, the cooperators asked if they could buy large amounts of cocaine, according to court documents. Then, they asked if the men could set up safe places in West Africa to store heroin on its way from Afghanistan to the United States, Canada and Europe.
