A Palestinian terrorist stabbed and killed an American tourist and injured at least 10 others in Tel Aviv on Tuesday, marking the third Palestinian attack within hours of one another.

Israeli police said the terrorist started to stab civilians near the entrance to the Jaffa Port entrance — wounding multiple individuals — before escaping toward Tel Aviv and stabbing motorists idling in their vehicles on the road.

Four of the victims are in serious condition, including a pregnant woman.

The attack occurred about a mile from the Peres Center for Peace, coinciding with Vice President Joe Biden‘s arrived at the facility to meet with former Israeli President Shimon Peres.

“Terrorist acts against children, women, and innocent people are intolerable,” said Biden in a joint press conference with Peres.

Hours earlier, Palestinian terrorists stabbed and injured three Israelis in two separate, nearly simultaneous attacks.

In Petah Tikva, a Palestinian terrorist repeatedly stabbed a 40 year-old ultra-Orthodox Israeli man in a wine store. After fleeing the scene temporarily, the victim returned to the store, pulled the knife out of his own neck and mortally stabbed the terrorist.

Around the same time, a Palestinian terrorist shot two Border Police officers in the head outside Nablus Gate in eastern Jerusalem. The two police officers are in critical and serious condition. Israeli police chased down and neutralized the gun-wielding assailant.

Earlier on Tuesday morning, an Arab woman in her 50s attempted to stab a Border Police officer in the Old City. The terrorist was shot dead on the scene.

Hamas praised Tuesday’s attacks and said that Israel’s attempts at stifling the violence are failing.

Israeli security forces believe Tuesday’s attacks are related and indicative of the Palestinian terrorism wave throughout the past five months that has claimed the lives of 34 Israelis.

The attacks have been largely characterized as individual initiatives, fueled by ongoing Palestinian incitement from social media circles and across the political spectrum.

Though most attacks are not attributed to any particular terrorist organization, official representatives of Hamas, Fatah and the Palestinian Authority (PA) glorify the murder of Israelis and encourage other Palestinians to emulate the terrorists.

For example, Fatah — the party of PA President Mahmoud Abbas — called for killing Israelis throughout the entire country in a music video broadcast on Fatah’s Awdah TV channel in January.

In February, senior Fatah official Sultan Abu al-Einein praised two teenaged terrorists and called them leaders for stabbing Israelis and killing a 21-year-old off-duty soldier. Notable Fatah and PA officials have repeatedly expressed support for Palestinian terrorists who attack Israelis by glorifying their images in official media outlets, attending government-sponsored funerals of terrorists, and providing financial assistance to their families.
