"Hamas' position is that unless Israel lifts the siege the situation will soon get out of control. A military conflict is just a matter of time," a Hamas official said.
Israel has placed the coastal enclave under a maritime blockade and tightly controls the land crossings with Gaza – measures imposed after the Hamas terrorist group usurped control of the Strip in 2007 in a military coup.
According to Arab media, a high-ranking Israeli delegation comprising intelligence and National Security Council officials arrived in Qatar on Sunday for talks on how Qatar could play a more meaningful role in the talks with Hamas.
Egypt is leading the efforts to broker a long-term ceasefire with the Gaza-based terrorist group.
According to the Hamas official, Gaza's rulers seek to avoid a full-fledged war.
"If Hamas wanted to aggravate the situation it would respond to the IDF's strikes [over arson terrorism] by firing thousands of rockets at Israel," he said.
A senior Israeli defense official noted that "further escalation is only a matter of time. Israel has no interest in hostilities, but the IDF is ready for any scenario."
