Bay Area protesters decry U.S. airstrikes on Iran amid global tensions

State of play: At least four protests, each planned by different groups, took place on Sunday alone, per NBC Bay Area.

• Signs and banners ranged from "Stop bombing Iran" to "Remember Hiroshima. Remember Vietnam."

Friction point: Near the Ferry Building Sunday afternoon, two groups of demonstrators got heated over differing views on the attacks, CBS Bay Area reports.

• Though many Iranian Americans are afraid the U.S.'s involvement will worsen the situation on the ground, some are also hopeful that it will end the current regime in Iran. (The Trump administration has said it's not seeking a regime change.)
• Heightened tensions led San Francisco police to intervene.

Yes, but: Politics aside, many are worried about their family in Iran.

What they're saying: "We don't know if there's going to be radiation issues from people that live close by. We don't know if they're all safe," Ardavan Amini, a member of the group Bay Area 4 Iran, told KTVU. "There's just a lot of unknowns right now."

What we're watching: U.S. officials have warned that travel disruptions, cyber attacks, demonstrations and heightened security presence are likely.
