They also talked about how to speed up the reconstruction process in the coastal enclave, Palestine.info reported.
The various Palestinian groups attending the meeting agreed on intensifying efforts to support Gaza and condemn the unjustified blockade of the coastal strip.
Israel heavily pounded the blockaded coastal sliver in a recent war that started on July 8 and ended on August 26 with an Egyptian-brokered truce.
Over 2,140 Palestinians, mostly civilians, including women, children, and the elderly, were killed in the 50 days of the Israeli onslaught on Gaza. Around 11,000 others were injured.
Gaza has been blockaded since 2007, which is a situation that has caused a decline in the standard of living, unprecedented levels of unemployment, and unrelenting poverty.
