Activists around the Bay Area took to the streets over the Martin Luther King Day holiday weekend, participating in four days of protests to bring attention to labor, housing and police brutality issues, including protests held at both the Oakland and San Francisco airports.

Around a hundred activists showed up at Oakland International Airport on Saturday evening to "welcome" travelers to the city with a "Say Their Name" rally, holding banners and reading out loud the names of people who have been shot and killed by local police officers.

The airport protest was but one of many events across the Bay Area, spanning the 96 hours between Martin Luther King, Jr.'s birthday, on January 15, and the federally observed holiday honoring the Civil Rights leader on January 18.

Among the protests was a rally on Friday to honor people shot and killed by Oakland Police in 2015. During one protest, coffins representing those killed were placed in a semi-circle outside of Oakland City Hall.

While the Oakland Police Department has long felt the ire of activists fighting charges of police brutality, it's actually the neighboring San Francisco Police Department that has faced more scrutiny in the last year.

The city was already reeling from an ongoing scandal involving racist texts exchanged by some officers when, in early December, a large group of police officers surround 26-year-old Mario Woods, armed only with a knife, and fired at least 15 shots, killing Woods.

Protesters also gathered for demonstrations related to gentrification and labor issues in Oakland. While so much attention has been paid to San Francisco's rent prices, in recent years Oakland's rental prices have increased at a rate that outpaces that of its expensive neighbor across the Bay.

Meanwhile, workers in Oakland making minimum wage saw a slight bump to start 2016 with hourly wages increasing by $0.30 an hour to $12.55.

Activists were planning to hold another "Say Their Name" rally on Sunday night, this time at the San Francisco airport. And organizers are holding a large rally on Monday, to bring the four days of events to a close. Similar "Reclaim MLK" protests have also been held elsewhere over the weekend, including in Chicago and St. Louis, both metro areas that have been at the center of similar Black Lives Matter protests over the last year.
