Israeli border policemen takes positions during clashes with Palestinians at the Hawara checkpoint near of the West Bank city of Nablus, on Sunday.

An Israeli airstrike in Gaza killed a pregnant Palestinian woman and her toddler, drawing a warning Sunday from Hamas, as unrest spun further toward a full-scale uprising.

After days of unrest in the West Bank and Israel, Gaza has been drawn into the violence since Friday, with clashes along the border leaving nine Palestinians dead from Israeli fire.

Israel’s military said it targeted “two Hamas weapon manufacturing facilities” overnight after Gaza militants fired two rockets and following Palestinian attempts to infiltrate southern Israel. One rocket hit an open field in southern Israel and the other was intercepted.

Israel’s airstrikes demolished a house in the northern Gaza area of Zeitun, killing Nur Hassan, 30, and her two-year-old daughter Rahaf, Gaza medics said.

In fresh clashes on the border in central and northern Gaza, Israeli soldiers fired warning shots in the air to try to disperse hundreds of stone throwing Palestinians, a military spokeswoman said.

In response to the air strike, a Hamas spokesman said “this shows the occupation’s desire to escalate.”

“We warn the occupation against continuing this foolishness,” said Sami Abu Zuhri. An explosion seriously wounded a Palestinian woman and lightly injured an Israeli policeman.

The Shin Bet internal security agency said as 31-year-old Israa Jaabis had tried to ignite a gas cylinder and was carrying leaflets in support of Palestinians killed by Zionist forces.
