UNITED NATIONS, Sept. 23 (Xinhua) -- UN Secretary-General Antonio Guterres on Friday condemned the violence in all forms witnessed in Haiti in recent weeks and called on all actors to work together to de-escalate the situation and ensure a return to calm, said his spokesman.

In the past weeks, Helen La Lime, head of the UN mission in Haiti, has further intensified her good offices with government representatives, political actors, civil society groups and private-sector stakeholders in search of a compromise on a peaceful transition leading to the restoration of democratically elected institutions, said Stephane Dujarric, the spokesman.

The UN mission continues to encourage Haitian stakeholders to engage in constructive discussions on ways to chart a common way forward and will continue to support Haitian-led efforts for a consensual transition arrangement, he told a daily press briefing.

UN humanitarians in Haiti are calling for an immediate end to attacks on humanitarian infrastructure and the looting of supplies, he said.

Following the attacks on UN-backed warehouses in different cities across Haiti, the UN resident and humanitarian coordinator, Ulrika Richardson, called for safe access for humanitarian workers and supplies and highlighted the important contribution of international and local nongovernmental organizations, which work often in volatile and dangerous situations across the country. Many of those organizations have been directly targeted by looters, said the spokesman.
