UN Special Coordinator for the Middle East peace process, Nickolay Mladenov, said in a tweet Sunday he welcomes "the recent statement by Hamas announcing the dissolving of [its] administrative committee in Gaza", and that he hoped "the Palestinian parties will use Cairo momentum to address the Gaza humanitarian situation".
It also was not immediate clear how Egypt's latest effort aligns with its previous tacit support for a separate Gaza power-sharing deal between Hamas and Mohammed Dahlan, an exiled former Abbas aide-turned-rival.
Al-Ahmed said the coming days will witness tangible practical steps starting with the national reconciliation government resuming its works in Gaza.
The group said it was "responding to the generous Egyptian efforts, which reflect the Egyptian desire to end the split and achieve reconciliation, and based on our desire to achieve national unity". Hamas and Fatah even waged a short civil war in Gaza in 2007 and ever since, Hamas has controlled Gaza.
The takeover led to rival governments, with Hamas controlling Gaza and Abbas in charge of autonomous enclaves in the Israeli-occupied West Bank.

Cricket Australia chief executive James Sutherland says he does not expect Australia to play in Pakistan "in the short term". After the 2009 attack on Sri Lankan team, only Zimbabwe toured the country for a bilateral series in 2015.
Despite the new accord, the Fatah group is insisting Hamas start implementing the deal before any further steps are taken. Repeated attempts at reconciliation have failed.
Ahead of Sunday's announcement, a Fatah delegation visited Cairo a day earlier to meet with Egyptian officials regarding the formation of a Palestinian unity government.
"Hamas has now made a fearless, serious and patriotic decision to dissolve the administrative committee (in Gaza)", Barhoum said.
Those reasons, coupled with an escalating sewage crisis that threatens the health of Gaza Strip residents and has ruined the Strip's beaches is contaminating the strip's beaches, and a crippling unemployment, have all contributed Hamas finally, maybe, crying Uncle.
However, Bjorn was skeptical if Hamas's announcement on Sunday would lead to a full-fledged reconciliation between Hamas and Fatah.
Hamas had previously demanded that Abbas halt a series of measures taken against Gaza before sitting down to discuss a reconciliation deal. However, in July 2014, Israel waged a large-scale military offensive on the Gaza Strip that last 50 days.
