Official celebrations, public entertainment programmes and ceremonial activities organised by ministries and government institutions have also been put on hold, while cultural venues, including Katara Cultural Village, have suspended festivities and musical performances. The Ministry of Transport also announced the suspension of all recreational and non-commercial maritime activities until further notice.

The organisers of SEAsters-in-Action 2026 announced the cancellation of this Saturday’s event, which was set to mark the 12th PADI Women’s Dive Day, citing the national mourning period and the current situation in Qatar. “With heavy hearts and after careful consideration, we have made the difficult decision to cancel this Saturday’s SEAsters-in-Action 2026 in observance of the national mourning period,” organisers Margaux De Pauw, Anusha Kandaiah and Michelle Anne del Carmen said in a joint statement.

Although the annual gathering has been called off, the organisers stressed that the initiative’s mission remains unchanged, highlighting their commitment to marine conservation and community engagement under this year’s PADI Women’s Dive Day theme, “Celebrate Community. Create Change”.The organisers also extended their heartfelt condolences to the people of Qatar during the mourning period, expressing hope for comfort, peace and strength for the nation. While many private organisers have adjusted their schedules or postponed activities, a number of malls, attractions, and businesses remain open, but with scaled-back entertainment and celebratory programmes in observance of the national mourning period.
