At least 20 people died and 70 were wounded Thursday when four bombs exploded at a market in the Iraqi capital.

A source with the Iraqi police told Efe that the four bombs had been planted in different parts of the market.

Some of the wounded are in serious condition and the number of fatalities could rise, the source said.

Besides the market blasts, a series of attacks around Baghdad and in other parts of Iraq killed 13 people and wounded about 20.

The most serious of those attacks took place in the Al Dura district in southern Baghdad, where seven people died and 15 were wounded when a bomb blew up at another market frequented by Chaldean Christians.

In another incident, the governor of western Al Anbar province, Ahmed al Doleimi, was unhurt in an assassination attempt.

A bomb exploded when the governor's convoy was passing and two of his bodyguards were wounded.

More than 800 people died last month in Iraq as a result of political or sectarian violence, bringing the civilian death toll for the year so far to around 5,000, the U.N. mission in Baghdad said.

Leaders of most of Iraq's political parties met last Thursday to sign a pact of "honor and social peace" to confront a resurgence of sectarian violence. EFE
