If the reports are true Pakistan should take up the matter, as should China's other close friends amongst Muslim states e.g. Saudi Arabia. It would be hypocritical not to.
But for the Indians to express their "concern" regarding Pakistan's stance is illogical considering their own government used to be, many years ago, quite concerned with what was going in Palestine. But over the last 20 year or so, the Israelis have become quite the close friends of New Delhi and so the unfortunate Palestinians don't even hear so much as a whimper of support from the Indians, regarding the numerous human rights abuses the Israelis commit on a daily basis. Seems like those Green Pine radars and Phalcon AWACS systems have had quite the numbing effect......
