Oliver Munro, 23, from Lossiemouth, has been in the West Bank since October with the International Solidarity Movement (ISM), which campaigns on behalf of Palestinians.

I'm staying in the West Bank village of Nil'in, near Ramallah. After the Gaza bombings on Saturday, hundreds of people took to the streets.

About 40 demonstrators were out on Sunday and seven members of ISM went with them. We started on the road into Nil'in and the army started using tear gas and rubber bullets. Then the protesters were splitting up, so the ISM volunteers split up too.

I ended up in a big olive field when we heard gunfire. There was screaming and people were panicking, running away. We saw two people dragged away by the crowd who were covered in blood.

When I got to the two men, they were completely lifeless. Arafat Khwaja, 21, had been shot in the back other reports suggest he had been shot in the chest and was dead. The other man, Mohamed Sadat Khwaja, was 19 and had been shot in the head. The funerals were held today.

The Palestinians I have spoken to refer to them as Shaheed, or martyrs. I think it's an attempt to turn something horrific and terrible into an act of defiance.

We have been positioned here because two children were killed by Israeli troops in summer, in the hope that our presence would help prevent further deaths. Yesterday's killings have come as a complete shock.
