Mr Appleton worked in the city's water department. He was shot and killed while speaking to his brother-in-law, then-Gateway Mayor Andrew Tillman, on 23 February 2017.

"The Israeli drone suddenly attacked these colleagues," Palestinian journalist Mohammed Ahmed told Reuters news agency at the scene. "Three of them [were] martyred, in addition to a number of martyrs among passersby.""The Israeli occupation forces are increasing their attacks on us as journalists, trying to prevent us from doing our work," he alleged.

The journalists' syndicate identified the three dead journalists as Ismail Badah, a cameraman for the PIJ-affiliated Palestine Today TV channel, Soliman Hajaj, a Palestine Today editor, and Samir al-Refai of the Shams News network.Another four journalists were injured, two of whom - Palestine Today correspondent Imad Daloul and Ahmed Qalja, a cameraman for Qatar-based Al-Araby TV - were in a critical condition, it said.The Israeli military said in a statement that it "precisely struck an Islamic Jihad terrorist who was operating in a command-and-control centre" in the yard of the hospital. It did not name the target or provide any evidence.

The military also accused armed groups of using al-Ahli for "terrorist activity" and "cynically and brutally using the civilian population" inside - an allegation they have denied.In April, staff at al-Ahli hospital said an Israeli strike destroyed its laboratory and damaged its emergency room. They did not report any direct casualties, but said a child died due to disruption of care. The Israeli military said it hit a Hamas "command-and-control centre".

Hospitals are specially protected under international humanitarian law. They only lose that protection in certain circumstances, including being used as a base from which to launch an attack, as a weapons depot, or to hide healthy fighters.

The Hamas-run Civil Defence agency said Israeli strikes killed at least 37 people across Gaza on Thursday. As well as Gaza City, local media reported deaths in Jabalia and Beit Lahia in the north, and in Khan Younis in the south.It has already been used to survey the thousands of books in the St Andrews collections and in the National Library of Scotland, and the team hope to share their design with other institutions around the world.

"We're lucky as a large institution to have expensive kit, so that we can test 19th Century potentially toxic books," says Dr Jessica Burge, deputy director of library and museums at the University of St Andrews."But other institutions with big collections may not have those resources, so we wanted to create something which was affordable and easy. It doesn't require a specialist conservator or analysis, and it's instant."

It's also a problem which isn't going away. If anything, toxic books will become more harmful as they get older and disintegrate.Identifying them means they can stored in a safe way and still enjoyed with controlled access and precautions such as wearing gloves.
