Palestinians gather in mourning outside the family home of 35-year-old professor and Hamas member Fadi Mohammad al-Batsh, who was killed early in the day in Malaysia, in Jabalia in the northern Gaza strip on April 21, 2018. Malaysian police said that the research scientist, who specialised in energy issues, was killed in a drive-by motorcycle shooting as he headed on foot to take part in dawn Muslim prayers on April 21 in Kuala Lumpur. His family accused Israel's Mossad spy agency of killing him. Photo by Ashraf Amra
