GAZA CITY, Gaza Strip — Thousands of Palestinians massed Friday along Israel’s frontier, with dozens approaching and breaching the perimeter fence that separates Gaza from Israel, even as Egypt stepped up efforts reach a lasting cease-fire between the territory’s Hamas rulers and Israel.

The militant Hamas group praised the turnout as a challenge to Israel, which was mulling a large-scale military response after a rocket was fired from Gaza on Wednesday and destroyed a house in southern Israel.
Gaza’s Health Ministry reported 77 Palestinians were wounded by Israeli fire and six of them were in serious condition.
“The Israeli enemy’s threats have effectively motivated the crowds to participate powerfully in the protest,” said Fawzi Barhoum, a spokesman for Hamas, which has staged the protests since March.
The large attendance was a test to Egypt’s efforts to push Hamas into scaling down the protests and rein in marchers who venture out to the fence and breach it, triggering deadly Israeli fire.
At least 156 Palestinians have been killed by Israeli fire since the protests began more than six months ago, and an Israeli soldier was killed by a Palestinian sniper.

Protesters Burnt Tires and Threw Rocks With Slingshots

Protesters Friday burnt tires and threw rocks with slingshots toward the heavily guarded fence. Hamas’ al-Aqsa TV aired footage of Palestinians climbing over the fence and others breaching it and entering into Israeli territory. Others used cutters to tear down parts of the barrier.

Israeli forces showered the demonstrators with tear gas and occasionally live fire.
In southern Gaza Strip, an aircraft hit a group of Palestinians launching flaming kites and balloons toward Israel near one protest location, the Israeli military said.
Earlier on Friday, the United Nations’ Mideast peace envoy urged Israel and the Palestinians to exercise restraint ahead of the protests.
“In light of today’s planned Gaza march, I urge all to exercise restraint, to proceed in a peaceful manner, and to avoid escalation,” Nickolay Mladenov said in a statement. “The U.N. is working with Egypt and its partners to avoid violence, address all humanitarian issues and support reconciliation.”

Egypt and the U.N. Have Attempted to Negotiate a Truce

Egyptian intelligence officials met with Hamas and Israeli officials on Thursday in efforts to broker a cease-fire and ease months of deadly border protests. Egypt and the U.N. have attempted to negotiate a truce between Israel and Hamas for weeks in a bid to ease tensions in the beleaguered Gaza Strip.
Hamas has said the protests will continue until there is an easing of the Egyptian-Israeli blockade of the Palestinian enclave that was imposed after the Islamic group seized control of Gaza from the Palestinian Authority in 2007 in an armed coup.
The protests have intensified in recent weeks as Egyptian and U.N. cease-fire negotiations have faltered, and cross-border violence earlier this week has brought tensions to a simmer.
On Wednesday, a rocket fired from the Gaza Strip destroyed a house in the Israeli city of Beersheba in the worst bout of violence in recent weeks. Israel retaliated with airstrikes and has beefed up its military forces along the border.
Israeli Prime Minister Benjamin Netanyahu’s Security Cabinet resolved to retaliate more severely to cross-border attacks, but has thus far refrained from further action, suggesting it was giving the Egyptians a chance to restore calm.
