Unlike Palestinians in the blockaded Gaza Strip and in the occupied West Bank, those living in occupied east Jerusalem have free access to the Jewish west of the city and to Israel.

Arab and Jewish populations do not mix extensively, but thousands of Palestinians work on Israel's roads and building sites. The gunman who attacked the seminary in March was from east Jerusalem. That attack was claimed by Hamas officials.

At Gaza's border crossing with Egypt, Egyptian forces used water cannon and Hamas security forces had to restrain a crowd jostling for access during a brief opening of the Rafah crossing point between the Palestinian enclave and its Arab neighbour.

Some Palestinians threw stones at Egyptian forces and also complained of Hamas's failure to speed their passage to Egypt, the only access to the outside world for most Gazans, who are blocked from other land, sea and air routes by Israel.
