The New York-based rights group said so-called "transnational repression" was having a "chilling effect" on political criticism and called on countries and international organisations to take action.

"Your house is ready. When you get out, you will be all set to find someone to marry!"

After the Gaza war ends, new Palestinian leaders are needed who could helm a future independent state, opposition figure Nasser al-Kidwa, the nephew of late Palestinian leader Yasser Arafat, told AFP.

"In a joint counterterrorism activity in the city of Jenin, IDF soldiers apprehended 14 suspects, killed three terrorists and struck additional terrorists," the army said in a statement.
