The Paris conference made no moves to address the occupation or pressure Israel.
Three air strikes on Monday night in the Gaza Strip killed nine members of the group, while an Israeli military operation in the West Bank left another dead.
Later on Tuesday morning, an Israeli air raid in the southern Gaza town of Khan Younis killed one of Hamas’s security-force members.
The raids came just hours after a conference in Paris attended by 90 countries pledged $7.4bn in aid over three years to the Palestinian Authority.

The first raid in Gaza City, late on Monday, killed Majed al-Harazin, commander of al-Quds Brigades for Gaza and the West Bank, a man wanted by Israel for the past nine years.
His car was reported to be full of explosives and a huge explosion could be heard across the city.
A second man was also killed in this attack.
Hundreds of Islamic Jihad fighters gathered in the streets and fired into the air after al-Harazin’s killing on Monday.
Three of the men died immediately, with a fourth man succumbing to his wounds in hospital hours later.
Meanwhile, in the occupied West Bank, 25-year-old Tarek Abu Rali, a local commander of the al-Quds Brigades, was killed by undercover Israeli soldiers as he drove in a car in the northern town of Jenin, medics and Islamic Jihad said.
Blow to peace
Mukhaimar Abu Sada, a political analyst from Gaza, told Al Jazeera that the Israeli attacks diminished hopes for a successful peace process.
But Matan Vilnai, Israel’s deputy defence minister, hailed the “successes”, saying the military was targeting the leadership of the group.

Speaking to the military’s radio station, he said: “The important thing is not the number of them who are hit, but their place in the organisation’s hierarchy.”
Al Jazeera’s correspondent David Chater said analysts in Gaza believe that the Israeli raids make a mockery of the peace process that started in Annapolis and continued in Paris with Monday’s aid conference.
He said Israel is holding back from a full-scale invasion into the Gaza Strip, mindful that it would not stop the rockets and mortars and would involve unacceptable casualties.
Israel has decided instead to hit harder at the cells responsible for the barrages, Chater said.
Ehud Barak, the Israeli defence minister, has told retired general Jim Jones, the recently appointed US envoy to the Middle East, that Israel must brace for the possibility of retaliatory attacks.
