Palestinians may be gratified to see American university campuses erupt in outrage over Israel's offensive in the Gaza Strip, but some in the embattled enclave are also wondering why no similar protests have hit the Arab countries they long viewed as allies.

Demonstrations have rocked universities in the United States this week, with confrontations between students, counter protesters and police, but while there have been some protests in Arab states, they have not been nearly as large or as vociferous.

"We follow the protests on social media every day with admiration but also with sadness. We are sad that those protests are not happening also in Arab and Muslim countries," said Ahmed Rezik, 44, a father of five sheltering in Rafah in Gaza's south.
