Britain has expressed "deep concern" over the killing of Turkish-American activist Ayse Nur Azgi Aygi by an Israeli sniper in the occupied West Bank on Friday.

"We are deeply concerned about the killing of Azgi Aygi," a British Foreign Office spokesman told Anadolu Agency on Saturday.

The spokesman explained that the killing of Azgi Aygi came against the backdrop of "the bloody violence that has been ongoing for weeks and is increasing day after day in the West Bank."

The spokesman stressed the need to protect civilians, noting that the British government continues to call on Israel to comply with international law.

On Friday, the Israeli army killed activist Aisha Nour with live bullets while she was participating in an activity denouncing settlements in the town of Beita in the Nablus Governorate in the northern West Bank.

Fouad Nafaa, director of Rafidia Hospital in Nablus, told Anadolu Agency that Aisha Nour arrived at the hospital with a bullet wound to the head, where she was "resuscitated, but she was martyred."

Aisha Nour worked in some food companies as well as a law firm, and volunteered with the International Solidarity Movement (ISM), which supported Palestinians in peaceful and civil ways against Israel's occupation of their lands.

American citizen Rachel Corrie, who was crushed to death by an Israeli bulldozer in 2003, belonged to the same movement.
