The Gazan fishermen's union is striking on Monday and Tuesday, in protest over the deadly Israeli policing of Gaza's waters, which resulted in the killing of a teenage fisherman on Sunday.
Amnesty's annual report notes the killing in December of "wheelchair user Ibrahim Abu Thurayya", who "was shot in the head by an Israeli soldier as he was sitting with a group of protesters near the fence separating Gaza from Israel".
The man was evacuated to a hospital in the southern Israeli city of Ashkelon, where he died of his wounds after undergoing surgery.
Hamas spokesman Abdel Latif Qanoua called the incident "an ugly crime the occupation is responsible for and a form of continuing aggression against our Palestinian people". In the West Bank, 13 Palestinians were wounded, eight of them by live fire and the others from rubber bullets, according to the ministry.
Over the past two years, Israel has detained dozens of Gaza fishermen who have strayed beyond the border, a senior naval commander said. The blockade specifically prohibits Palestinians from fishing beyond six nautical miles (11 kilometers) off the coastline.
Israel waged a devastating 51-day military onslaught on the Gaza Strip in mid-2014 in which more than 2,300 Palestinians were killed and tens of thousands injured.
Israel occupied the West Bank, including East Jerusalem, during the 1967 Middle East war.
