Unrwa has the capacity and expertise to support a postwar Gaza. We want to help make this peace work | Philippe Lazzarini

With a ceasefire in place, rebuilding must begin, justice be delivered and healing seriously addressed by Palestinian and Israeli societies

• Philippe Lazzarini is the commissioner-general of Unrwa

After two years of brutal warfare in Gaza, a fragile ceasefire - the first phase of US president Donald Trump's 20-point plan - offers some respite to an exhausted population. For my Unrwa colleagues on the ground in Gaza, the constant fear of being killed by bombs and guns may have abated, but there is still much to worry about - access to shelter, food and clean water remains challenging, and winter is approaching fast.

There is no time to lose in tackling widespread hunger and disease. The scale of physical and psychological trauma is immense, and expectations about access to healthcare and education are growing. The next weeks and months will determine whether this watershed moment will lead to a new dawn or be a prelude to greater despair.
