More than a week of fighting between Israel and Hamas showed few signs of abating on Tuesday despite intense US and global diplomacy to stop the region's fiercest hostilities in years.
The Israeli military said late on Monday that Hamas and other Palestinian groups had fired about 3,350 rockets from Gaza - 200 of them on Monday alone - and that Israeli air and artillery strikes had killed at least 130 militants.
Gaza health officials put the Palestinian death toll at 212, including 61 children and 36 women, since hostilities began last week. Ten people have been killed in Israel, including two children.
Amid seemingly fruitless diplomatic efforts to stop the violence, the top US military officer, Army General Mark Milley, warned that the violence could spread, Reuters reports.
"My assessment is that you risk broader destabilisation and you risk a whole series of negative consequences if the fighting continues," Milley, chairman of the Joint Chiefs of Staff, told reporters before landing in Brussels on Monday for talks with NATO allies. "It's in no one's interest to continue fighting."
Around midnight, six shells were fired from Lebanon towards northern Israel, but fell short of crossing the border, the Israeli military said, adding that it fired artillery at "the sources of the launches" in Lebanon.
The United Nations Interim Force in Lebanon (UNIFIL) said that it was intensifying patrols after it detected the firing of rockets from the area of Rashaya Al Foukhar, north of Kfar Choub in southern Lebanon.
UNIFIL added on Twitter that the situation in the area was now calm and that its head of mission remained in contact with all parties to ensure stability. Israel fought a 2006 war against Hezbollah guerrillas, trading rockets and air strikes, but the border has since been mostly quiet.
DIPLOMATIC EFFORTS
US President Joe Biden expressed his support for a ceasefire during a call with Israeli Prime Minister Benjamin Netanyahu on Monday, the White House said in a statement.
But Netanyahu told Israelis earlier that strikes against militant sites and leaders in Gaza would carry on.
"The directive is to continue to strike at terror targets," he said in a televised speech, after meeting with military and intelligence chiefs. "We will continue to act as necessary to restore peace and security to all residents of Israel."
The armed wing of Hamas promised more rockets in return: “The criminal Zionist enemy intensified its bombing of homes and residential apartments in the recent hours, and therefore, we warn the enemy that if it did not stop that immediately, we would resume rocketing Tel Aviv,” said spokesman Abu Ubaida.
US Secretary of State Antony Blinken urged all sides to protect civilians.
Although stressing that Israel had the right to defend itself, Blinken said he had not seen any evidence from Israel about its suggestion that Hamas was operating out of a building housing media outlets - including the US-based Associated Press - which was destroyed in an Israeli missile strike at the weekend.
Hamas denied having offices in the building. "These are false allegations and an attempt to justify the crime of targeting a civilian tower," said Hamas spokesman Fawzi Barhoum.
Egypt and UN mediators also stepped up diplomatic efforts, while the UN General Assembly will meet to discuss the violence on Thursday.
The Biden administration approved the potential sale of $735 million in precision-guided weapons to Israel, and congressional sources said on Monday that US lawmakers were not expected to object to the deal.
COMMUNAL VIOLENCE
Hamas began its rocket assault last Monday after weeks of tensions over a court case to evict several Palestinian families in East Jerusalem, and in retaliation for Israeli police clashes with Palestinians near the city's al-Aqsa Mosque, Islam's third-holiest site, during the Muslim holy month of Ramadan.
The hostilities between Israel and Hamas-controlled Gaza have been accompanied by an uptick of violence in the West Bank, where the Palestinians have limited self-rule.
There have also been clashes between Israel's Jewish and Arab communities in mixed areas.
Israel's president has warned that tension between Jewish and Arab Israelis could devolve into "civil war".
General strikes are planned for Tuesday in Arab towns within Israel and Palestinian towns in the West Bank, with posts on social media urging solidarity "from the sea to the river."
