The Qatari foreign ministry, in a statement, said it stresses that continued bombing at the end of the pause "complicates mediation efforts and exacerbates the humanitarian catastrophe in the Strip, and... calls on the international community to move quickly to stop the violence."
It added "its condemnation of all forms of targeting civilians, the practice of collective punishment, and attempts to forcibly displace and displace citizens of the besieged Gaza Strip, and its demand for an immediate ceasefire."
Qatar has been engaged in intense negotiations, with support from Egypt and the United States, to repeatedly prolong a truce in Gaza that had lasted a total of seven days after two extensions.
The agreement was designed to be continued if Hamas could release 10 captives per day.
But after the truce expired on Friday morning, the Israeli army said its combat operations had resumed.
Qatar's foreign ministry confirmed negotiations between Israel and Hamas "are continuing with the aim of returning to a pause".
The emirate added it was "committed, along with its mediation partners, to continuing the efforts that led to the humanitarian pause and will not hesitate to do everything necessary to return to calm".
