On 16 May 1967, Egypt ordered the UNEF out of Sinai and reoccupied it militarily. Secretary-General U Thant eventually complied and ordered the withdrawal without Security Council authorisation. In the course of the Six-Day War that broke out shortly thereafter, Israel occupied the entire Sinai Peninsula, and Gaza Strip from Egypt, the West Bank (including East Jerusalem) from Jordan (which Jordan had controlled since 1949), and the Golan Heights from Syria. The Suez Canal, the east bank of which was now occupied by Israel, was closed. Israel commenced efforts at large scale Israeli settlement in the Sinai Peninsula.
