A prominent Palestinian American Al-Jazeera reporter was shot dead during an Israeli raid in the occupied West Bank on Wednesday, and Israel said it was launching an investigation to try to determine who killed her.

Veteran journalist Shireen Abu Akleh, 51, was wearing a press vest that clearly marked her as "Press" while reporting in the city of Jenin, the Qatar-based outlet said.

She was covering the latest arrest operation launched by the Israeli military amid deadly Arab attacks in Israel.
