Doha (Quds News Network)- Qatar's Foreign Ministry will hold a news conference on Wednesday in Doha where the country has been hosting talks towards a Gaza ceasefire deal, a senior Qatari official said. Earlier, an invitation by Qatar's state news agency said the news conference would be hosted by Prime Minister Sheikh Mohammed bin Abdulrahman Al Thani, who is also foreign minister. The official declined to say what time the news conference would begin, apart from that it would be held later on Wednesday evening. If a deal is finalized, implementation would likely start on Sunday, sources told CNN. Hamas is expected to release 33 captives during the first phase of an emerging deal. Hundreds of Palestinian prisoners are set to be released from Israeli jails at the same time. The release of the captives would be the first phase of the deal being finalized. Negotiations to reach the second phase – which is intended to end the war – would begin on the 16th day of the implementation of the deal.
