Iraq's Interior Ministry says nine people have been killed and at least 31 others wounded in a bombing at a cafe in Iraq's capital.

Ministry officials say the blast occurred late Wednesday in a mostly Shi'ite district of southwestern Baghdad.

Despite recent violence, the Iraqi government says casualties dropped to an all-time low last month, after a bloody month of April.

The report issued Sunday said 165 Iraqis, including 134 civilians, were killed in May from insurgency-related violence.  Authorities reported 355 deaths in April.

The Iraqi military is under pressure to show it can secure the country before June 30, when U.S. combat troops pull out of major cities and return to their bases.
