Mayor Stephanie Rawlings-Blake said keeping the city safe remained her top priority, and that a 10:00 pm to 5:00 am curfew remained in effect until further notice.
"I have made no decision about lifting the curfew. We re-evaluate on a daily basis," she told CNN.
"We're going to make sure that we keep our young people safe. I don't want to lose another life out on the Baltimore streets because of the violence that has been erupting in our city."
Trouble began after a funeral was held for 25-year-old Freddie Gray, who died of severe spinal injuries on April 19, a week after he was arrested by police.

The city has been the site of daily demonstrations since Gray's death, as tensions simmer over alleged police brutality and discrimination against African Americans.
Rawlings-Blake has denounced the violence, and reiterated calls for calm.
"We want peace in our community. And we're going to do everything that we can to ensure that we have peace moving forward," she said.
Amid the demonstrations, the Baltimore Orioles postponed two Major League Baseball games against the Chicago White Sox this week and Wednesday's contest at Camden Yards was closed to the public.
