Countries worldwide have appealed for calm after days of unrest spiraled into retaliatory attacks by Israel and Palestinians.
The US, the European Union and the UK have urged Israel and the Palestinians to lower tensions as soon as possible.
The violence escalated on Monday night after Palestinian militants fired rockets towards Jerusalem.
In response, the Israeli military launched air strikes against militant targets in the Gaza Strip.
Palestinian health officials in Gaza said 22 people, including nine children, had died in the strikes while Israel’s military said at least 15 members of the Hamas group that rules Gaza were among those killed.
Hamas had threatened to strike after hundreds of Palestinians were injured in clashes with Israeli police at a holy site in Jerusalem yesterday.
