In the main, they aren't citizens.
Generally, they share little in common. They have no common culture, common language, common worldview, common territorial desires, common religious views, and common economic views. In short, they just happen to be two different groups of people who want the same land.
No. It is very rare, but the probability increases if you talking about Arab Israelis and Palestinians (as opposed to Jewish Israelis and Palestinians).

The Israelis and Palestinians are fighting over a small piece of land called the Gaza Strip and the West Bank.The Israelis and Palestinians are fighting about a wide variety of things. Please see the Related Question to read more about the conflict.
Peaceful co-existence.
There is an ethnic and national conflict between Israelis and Palestinians and therefore there are several cases of Israeli Security Forces torturing Palestinians. Additionally, a number of the laws used in the Occupied Territories are subject only to Israeli Military Review which prevents Civil Law from taking action to prevent such abuses. However, it is incorrect to assume that all Israelis or even most Israelis torture Palestinians.
It began with the religious conflicts where Palestinians were not ready for peace.
Yes. There are land disputes between Israelis and Palestinians and the land in dispute is located in Southwest Asia.
The West Bank
Yes, they do. See the related question on why that might be.
No. Neither of them are fighting "the Muslims" as a group. Most Palestinians are Muslims anyway. The Israeli-Palestinian Conflict is between two national groups: Israelis who are primarily Jewish against Palestinians who are primarily Muslim. However, neither Israeli nor Palestinian forces have declared that they are fighting Islam. There are numerous mosques in both countries where Muslim worshipers freely pray to God.
If you do a search on the web of casualty numbers for all wars and conflicts between Israelis and Palestinians, you can find the numbers although there are many different reports on numbers especially on the Arab side which is less exact. I took the higher estimates for all and counted approximately 19,000 Palestinians killed by Israelis and 18,885 Israelis killed by Palestinians and other Arabs since the start of the conflict in the 1920s. Also note that a further 18,300 Palestinians were killed by other Arab groups (Black September, War of the Camps, etc.). The amount of Israeli casualties from only conflicts with the Palestinians ranges from 2,000-3,000 individuals.
