There are protests against an Israeli court ruling to evict Palestinian families in the Sheik Jarrah area of East Jerusalem.
Tensions have been rising for the past week.
On Monday, Israel celebrates the conquest of Jerusalem in the Six-Day War in 1967. A day that was already suspected in advance could be even more chaotic.
Hundreds of people are said to have been injured in clashes between Palestinian protesters and Israeli police.
The Palestinian organization Hamas has said that Israel "plays with fire" after the decisions on evictions.
Israeli Prime Minister Benjamin Netanyahu has defended the Israeli police, saying "Israel is acting responsibly".
The UN Security Council will meet later today to discuss the crisis.
