Israeli security forces have expanded a military operation to Nur Shams in the West Bank, a military spokesperson said on Sunday.
The military, police and intelligence services launched a so-called "counter-terrorism operation" in Jenin on January 21, described by officials as a "large-scale and significant military operation.”
The Israeli military said several militants had been killed and a number of wanted suspect detained in the operation.
A pregnant 23-year-old Palestinian was killed by Israeli security forces on Sunday in the Nur Shams refugee camp, the Palestinian health ministry said.
Sundos Jamal Mohammed Shalabi, who was eight months pregnant, was struck by Israeli gunfire, the ministry said in a statement, adding that the fetus also did not survive and that Shalabi's husband was critically injured.
The Palestinian state news agency cited eyewitnesses as saying that Shalabi and her husband were shot by Israeli forces as they were trying to leave their home.
Thousands of Palestinians have fled West Bank homes in the wake of the military campaign in the West Bank and the widespread destruction.
Palestinians have said the Israeli campaign is one of the most destructive in recent memory. Dozens of Palestinians have been killed, according to the Palestinian Authority’s Health Ministry.
