The United Nations on Tuesday hailed an Israeli decision to open the Kerem Shalom crossing to allow aid into Gaza, and urged the opening of a second location to let in humanitarian workers. "We very much welcome the Israeli authorities' opening of Kerem Shalom crossing for essential humanitarian supplies," Jens Laerke, a spokesman for the UN humanitarian agency OCHA, told reporters in Geneva, saying the Erez crossing should also be opened. nl/rjm/jv
