This report aims to inform humanitarian decisions and planning by summarising key developments that affected the humanitarian situation in Yemen in 2020 and highlighting issues to watch in 2021. In the past six years, the war between the Houthis and the IRG has killed over 18,400 civilians in Yemen. Nearly 2,000 of these deaths occurred in 2020. In the same year, there were several attempts at peaceful solutions or ceasefires. While these attempts contributed to decreased civilian casualties and resulted in smaller pockets of conflict, the agreements were usually bilateral and focused on a specific location and/or issue, making them fragile and often brief.
