Hamas accuses Israel of endangering Gaza truce by delaying release of Palestinian prisoners under the deal due to the manner in which it freed Israeli hostages. Tensions are rising as the first phase of the truce is set to end in March and details of the subsequent phase have not been agreed upon. Israel has announced an expansion of military operations in the occupied West Bank, sending a tank division to the city of Jenin. Both sides have accused each other of ceasefire violations, but the truce has held so far.
