Hamas and Fatah have signed a reconciliation deal in Cairo، ending a decade-long rift between the two Palestinian factions، BBC News reported.
The deal is believed to cover security، administrative and border crossing arrangements in the Gaza Strip.
Egypt has been brokering the reconciliation talks in Cairo.
Palestinians in Gaza and the West Bank have been ruled separately since deadly clashes between the two groups broke out in 2007.
Hamas won parliamentary elections in the occupied territories the previous year، and reinforced its power in Gaza after ousting Fatah from the enclave.
Palestinian President Mahmoud Abbas said on Thursday that the talks had led to a "final agreement" to end the rival split.
"I welcome the agreement،" he told the AFP news agency، adding: "I received a detailed report from the Fatah delegation about what was agreed and I considered it the final agreement to end the division."
Mr Abbas is reportedly planning to travel to the Gaza Strip in the coming weeks in what would be his first visit to the territory in a decade.
Details of the agreement are due to be announced later on Thursday.
