I guess all the issues started after fall of Ottaman ruling after 1st world war.

Yes and no. For a better understanding the issues, MANDATES PALESTINE REPORT of the PALESTINE ROYAL COMMISSION aka PEEL REPORT presented in 1937, should be read.
"In order to obtain Arab support in the War, the British Government promised the Sharif of Mecca in 1915 that, in the event of an Allied victory, the greater part of the Arab provinces of the Turkish Empire would become independent. The Arabs understood that Palestine would be included in the sphere of independence."
"In order to obtain the support of World Jewry, the British Government in 1917 issued the Balfour Declaration. The Jews understood that, if the experiment of establishing a Jewish National Home succeeded and a sufficient number of Jews went to Palestine, the National Home might develop in course of time into a Jewish State."
First issue caused by words given to two different ethnic groups on the very same land.
"These hopes proved unfounded because, although Palestine as a whole became more prosperous, the causes of the outbreaks of 1920 and 1921, namely, the demand of the Arabs for national independence and their antagonism to the National Home, remained unmodified and were indeed accentuated by the "external factors," namely, the pressure of the Jews of Europe on Palestine and the development of Arab nationalism in neighbouring countries.
These same causes brought about the outbreaks of 1929 and 1933. By 1936 the external factors had been intensified by--
(1) the sufferings of the Jews in Germany and Poland, resulting in a great increase of Jewish immigration into Palestine; and
(2) the prospect of Syria and the Lebanon soon obtaining the same independence as Iraq and Saudi Arabia. Egypt was also on the eve of independence."
Mandate administration couldn't estimate and handle "external factors."
"Up till now the Arab cultivator has benefited on the whole both from the work of the British Administration and the presence of Jews in the country, but the greatest care must now be exercised to see that in the event of further sales of land by Arabs to Jews the rights of any Arab tenants or cultivators are preserved. Thus, alienation of land should only be allowed where it is possible to replace extensive by intensive cultivation. In the hill districts there can be no expectation of finding accommodation for any large increase in the rural population. At present, and for many years to come, the Mandatory Power should not attempt to facilitate the close settlement of the Jews in the hill districts generally.
The shortage of land is due less to purchase by Jews than to the increase in the Arab population. The Arab claims that the Jews have obtained too large a proportion of good land cannot be maintained. Much of the land now carrying orange groves was sand dunes or swamps and uncultivated when it was bought."
Crucial point. Arabs were selling their lands to Jews, and this action was mainly funded by Jewish National Fund. In the 1930s, most of the land was bought from landowners. Of the land that the Jews bought, 52.6% were bought from non-Palestinian landowners, 24.6% from Palestinian landowners, 13.4% from government, churches, and foreign companies, and only 9.4% from fellaheen (farmers). On 31 December 1944, out of 1,732.63 dunums of land owned in Palestine by large Jewish Corporations and private owners, about 44% was in possession of Jewish National Fund.
"The problem of immigration has been aggravated by three factors:-- (1) the drastic restrictions imposed on immigration in the United States, (2) the advent of the National Socialist Government in Germany, and (3) the increasing economic pressure on the Jews in Poland.
Restrictions on Jewish immigration will not solve the Palestine problem. The National Home seems already too big to the Arabs and, whatever its size, it bars the to their attainment of national independence."
Yet another great mistake.
"An irrepressible conflict has arisen between two national communities within the narrow bounds of one small country. There is no common ground between them. Their national aspirations are incompatible. The Arabs desire to revive the traditions of the Arab golden age. The Jews desire to show what they can achieve when restored to the land in which the Jewish nation was born. Neither of the two national ideals permits of combination in the service of a single State.
The problem cannot be solved by giving either the Arabs or the Jews all they want. The answer to the question which of them in the end will govern Palestine must be Neither. No fair-minded statesman can think it right either that 400,000 Jews, whose entry into Palestine has been facilitated by he British Government and approved by the League of Nations, should be handed over to Arab rule, or that, if the Jews should become a majority, a million Arabs should be handed over to their rule. But while neither race can fairly rule all Palestine, each race might justly rule part of it."
"The advantages to the Arabs of Partition on the lines we have proposed may be summarized as follows:--
(i) They obtain their national independence and can co-operate on an equal footing with the Arabs of the neighbouring countries in the cause of Arab unity and progress.
(ii) They are finally delivered from the fear of being swamped by the Jews, and from the possibility of ultimate subjection to Jewish rule.
(iii) In particular, the final limitation of the Jewish National Home within a fixed frontier and the enactment of a new Mandate for the protection of the Holy Places, solemnly guaranteed by the League of Nations, removes all anxiety lest the Holy Places should ever come under Jewish control.
(iv) As a set-off to the loss of territory the Arabs regard as theirs, the Arab State will receive a subvention from the Jewish State. It will also, in view of the backwardness of Trans-Jordan, obtain a grant of £2,000,000 from the British Treasury; and, if an agreement can be reached as to the exchange of land and population, a further grant will be made for the conversion, as far as may prove possible, of uncultivable land in the Arab State into productive land from which the cultivators and the State alike will profit."
"The advantages of Partition to the Jews may be summarized as follows:--
(i) Partition secures the establishment of the Jewish National Home and relieves it from the possibility of its being subjected in the future to Arab rule.
(ii) Partition enables the Jews in the fullest sense to call their National Home their own; for it converts it into a Jewish State. Its citizens will be able to admit as many Jews into it as they themselves believe can be absorbed. They will attain the primary objective of Zionism--a Jewish nation, planted in Palestine, giving its nationals the same status in the world as other nations give theirs. They will cease at last to live a minority life."
As we see they didn't consider that two partitions might conflict and invade each other at all. It was a dead born solution. It was foolishly optimistic to state that "Partition offers a possibility of finding a way through them, a possibility of obtaining a final solution of the problem which does justice to the rights and aspirations of both the Arabs and the Jews and discharges the obligations undertaken towards them twenty years ago to the fullest extent that is practicable in the circumstances of the present time."
In brief, Palestine issue is a huge tumulus of past mistakes. Pretty long story on a bloody ground.
