Yemeni security forces fired warning shots to break up a rally by thousands of demonstrators Thursday calling for a boycott of parliamentary elections.
Demonstrators say at least 10 people were wounded and another 10 arrested during Thursday's clashes in the capital Sanaa.
Thousands of protesters gathered in Sanaa to oppose the planned April vote. They say they will not take part unless the government reforms the nation's electoral laws to prevent vote-rigging and other fraud.
In southern Yemen Thursday, foreign media report that two people were killed in the explosion of a explosive-laden motorcycle. The Reuters news agency quotes a security official saying the dead were Islamist militants whose bombs went off accidentally.
Yemeni officials have arrested numerous suspected militants in recent months, including 25 said to be linked with the September attack near the U.S. Embassy in Sanaa.
