BAGHDAD (AP) -- Iraq's Interior Ministry says security is being tightened in Baghdad following bombings that have killed at least 20 people.
A government statement says the added security will include more undercover agents on the streets.
The deadliest of today's bombs reportedly tore through a minibus carrying Iraqi government employees. An official says 13 people were killed, eight of them women. Another three people are said to be wounded.
Elsewhere in Baghdad, an Interior Ministry official says a female suicide bomber waiting to be searched at a checkpoint near the Green Zone blew herself up. The official says seven people were killed and 13 wounded.
Two other bombings, one of them northeast of Baghdad, reportedly took another three lives.
