This has been coming for some time, Israel has immense security problems with out having to deal with migrants, who do not want to or in some situations can not assimilate into the Israel community. Some where brought in on an assumption that they where from the tribes of Israel, others say that was just a scam, to bring in low cost workers and not abuse the percentage of Jews, required in Israel. In any case it has not worked out as expected, and the migrants, are turning out to be more trouble than they are worth to the country, so this is there answer. You must remember Israel is a very small country, and 20 thousand migrants can be a huge problem. But expect more violence before this is over, and the protests are just beginning. The liberal Israelis are a powerful voice, and will be heard.
