TEL AVIV, Aug 19 (Reuters) - U.S. Secretary of State Antony Blinken said on Monday Israeli Prime Minister Benjamin Netanyahu had accepted a "bridging proposal" presented by Washington to tackle disagreements blocking a ceasefire deal in Gaza, and urged Hamas to do the same.

Blinken spoke to journalists after a day of meetings with Israeli officials, including a 2-1/2-hour meeting with Netanyahu. The top U.S. diplomat had said earlier that this push was probably the best and possibly last opportunity for a deal.

Talks in Qatar seeking a ceasefire and hostage return agreement last week paused without a breakthrough, but were expected to resume this week based on the U.S. proposal to bridge the gaps between Israel and Hamas.

Blinken's visit comes as U.S. President Joe Biden, opens new tab faces mounting election-year pressure over his stance on the conflict, with his Democratic party starting its national convention on Monday amid pro-Palestinian protests and worries about Muslim and Arab American votes in swing states.

However, with the Palestinian Islamist group announcing a resumption of suicide bombing inside Israel after many years, and claiming responsibility for a blast in Tel Aviv on Sunday night, and medics saying Israeli military strikes killed at least 30 Palestinians across the Gaza Strip on Monday, there are few signs of conciliation on the ground and fears of wider war.

"In a very constructive meeting with Prime Minister Netanyahu today, he confirmed to me that Israel accepts the bridging proposal - that he supports it," Blinken told reporters in Tel Aviv.

"It's now incumbent on Hamas to do the same, and then the parties, with the help of the mediators - the United States, Egypt and Qatar - have to come together and complete the process of reaching clear understandings about how they'll implement the commitments that they've made under this agreement."
