( CNN ) First , a 20-year-old Israeli was stabbed Monday at a bus stop in Tel Aviv . Then , three Israelis were stabbed at a hitchhiking post near the entrance to a settlement in the West Bank , police said . One of the three , a 24-year-old woman , was killed , emergency services said . In both incidents , the attackers were `` terrorists , '' police said . The incidents came amid simmering tensions -- not just between Israel and Palestinians , but between rival Palestinian factions as well . `` The atmosphere of violence rides the wave of Palestinian incitement , '' Israeli military spokesman Lt. Col. Peter Lerner said on Twitter . After the Tel Aviv stabbing , a Palestinian suspect from Nablus in the West Bank was arrested `` with the help of eyewitnesses while he was hiding in an apartment building in the fourth floor nearby the central bus station , '' police spokeswoman Luba Samri said . The victim , a member of the Israel Defense Forces , was taken to a hospital in serious condition , police said . After the stabbings at the Alon Shvut junction in the West Bank , the attacker was shot by a security guard , police said . The junction is the same site where three Israeli teens were kidnapped and later found dead , ultimately sparking an Israeli military campaign targeting Hamas in Gaza called Operation Protective Edge . The incidents Monday -- the latest in a string of attacks -- came amid a new round of infighting between Palestinian factions . The political party Fatah said Sunday it will scrap a series of events to commemorate the death 10 years ago of Palestinian leader Yasser Arafat . The group blamed rival faction Hamas , saying it is behind a series of bombings at the homes of Fatah leaders . Hamas denounced the attacks , according to the Facebook page of spokesman Sami Abu Zuhri . Fatah controls the West Bank , and Hamas controls Gaza . While the parties have fought violent battles in the past , they 've made repeated announcements of plans to form a unity government as well . On Saturday , Israeli police shot and killed a Palestinian man who attacked police officers with a knife in a village in northern Israel , police said . There were conflicting accounts of exactly what happened . Israel has been facing what some call an `` auto intifada '' -- a spate of attacks on Jewish civilians in Jerusalem by Palestinians driving vehicles . Hamas said it `` blesses the action . What is happening in Jerusalem is pushing us to prepare for war . '' Violence has recently involved the Temple Mount , the holiest site in Judaism and one of the three holiest sites in Islam . It 's known to Muslims as Haram al-Sharif , or the Noble Sanctuary , and Jews are allowed to visit the site but not to pray there . A Palestinian recently shot and critically wounded a rabbi , Yehuda Glick , who campaigns for the right of Jews to pray at the site . After an Israeli counterterrorism unit shot and killed the assailant hours later , Palestinian Authority President Mahmoud Abbas -- part of Fatah in the West Bank -- wrote to the assailant 's family saying he would `` go to heaven as a martyr defending the rights of our people and its holy places .
