Israel said on Tuesday pressure groups were pushing foreign courts to take action against Israelis over alleged war crimes in Gaza but described the actions as "propaganda activity" and said no warrants had been issued. The International Criminal Court has issued arrest warrants against Israeli Prime Minister Benjamin Netanyahu and former Defence Minister Yoav Gallant, as well as a Hamas leader, Ibrahim Al-Masri, over alleged war crimes in Gaza. The warrants sparked outrage in Israel but also drew fears that similar warrants could be issued against Israelis who served in the military in Gaza. On Sunday, an Israeli reservist on holiday in Brazil left the country after a Brazilian federal judge in Salvador ordered police to open an investigation into allegations that he had committed war crimes while serving with the military in Gaza. The Hind Rajab Foundation, the pro-Palestinian group which brought the action, said it had filed evidence of alleged war crimes with the ICC against 1,000 Israelis, including video and audio reports, forensic reports and other documentation. The ICC confirmed it had received a filing and said it would "analyze the materials submitted, as appropriate". Israel's foreign ministry offered assistance to the reservist singled out by the action but officials said the issue was not widespread. The military has warned reservists that they could face arrest abroad over alleged war crimes in Gaza, according to documents published by Israeli media.
