The Israeli military says it has arrested 10 Palestinians suspected of throwing rocks at Israeli cars and causing a crash that badly injured a 2-year-old Israeli infant.

The car crash took place Thursday near the West Bank settlement of Ariel. The army said in a statement that it considers the rock throwing as "terror."

Police spokesman Micky Rosenfeld says an Israeli mother driving her three daughters crashed at the time of the rock throwing. He said the police assume the rocks caused the crash, but are still investigating.

Hospital officials say the Israeli infant is in critical condition.

Police say Palestinians also threw rocks Thursday at an Israeli bus in east Jerusalem.

Police are on high alert Friday for demonstrations by Muslim worshippers at a holy site in Jerusalem.
