Police in Somalia say at least ten people were killed in a suspected car bomb attack in the capital Mogadishu.
The blast went off at a police checkpoint near a busy market.
There was no immediate claim of responsibility but the Somali Islamist group al-Shabaab has previously carried out such attacks in the city.
"The whole market is ruined and people perished. The death toll is sure to rise," a colonel in the police force said.
He said at least ten people had been confirmed dead so far, while a dozen more were wounded.
Somalia is still battling an Islamist insurgency while it seeks to rebuild after more than two decades of conflict and chaos that have left the nation in tatters.
It is holding a vote at polling centres across the country over several weeks for a new parliament.
Around 14,000 people representing Somalia's federal states have been chosen to picket the 275 lawmakers. Those members of parliament will choose a new president.
The government, UN officials and international donors have said security issues prevented a broader vote.
The parliamentary vote was due to end on 30 November, after several delays, but an official said it was now likely to last until mid-December.
Al Shabaab accuses the presidential and parliamentary candidates of being foreign stooges.
