A Palestinian attacker stabbed and wounded a pregnant Israeli woman in the West Bank on Monday before being shot, Israeli officials said.

The attacker entered the Tekoa settlement and stabbed the 30-year-old woman, the Israeli military said, before being shot by the settlement's head of security.

Shoham Ruvio, a spokeswoman for Jerusalem's Shaarei Tzedek hospital, said the woman was five months pregnant. She said the woman was moderately wounded after being stabbed in the upper body. Ruvio said there was no damage caused to the fetus. Ruvio identified the woman as Michal Froman, the daughter-in-law of a late settler rabbi known to promote coexistence between Arabs and Jews.

Eli Bin, the head of Israel's rescue service MDA, had earlier told Israeli Channel 10 TV that the woman was seriously wounded.

The attacker's condition was not immediately known.

Monday's attack was the latest in a four month-long wave of violence that shows no sign of abating. Palestinian attacks have killed 25 Israelis and an American student. At least 146 Palestinians have been killed by Israeli fire, of whom 101 are said by Israel to have been attackers. The rest have been killed in clashes with Israeli troops.
