Iraqi police say a bomb exploded in a crowded animal market in central Baghdad Friday, killing at least 13 people.
Authorities say nearly 60 others were wounded in the blast, including several police officers.
The Souq al-Ghazl market in Baghdad also was bombed earlier this year.
In the northern city of Mosul, police say a suicide car bombing targeting a police patrol killed at least nine people, including at least three policemen.
Today's explosions came amid a decrease in violence across the nation.
In separate news today, Polish Prime Minister Donald Tusk said his government will withdraw all of its troops from Iraq in 2008. Poland has about 900 soldiers in southern Iraq.
