Israel and Hamas on Wednesday accused each other of obstructing negotiations for a ceasefire in the Gaza Strip, after Israel withdrew its negotiators from the talks the previous day. Israeli media reported on Wednesday that the refusal by the Palestinian Islamist militia Hamas to hand over a list of the names of the hostages it still holds is hindering progress in the negotiations.

CAIRO — Israel and Hamas appear closer than they have been in months to agreeing to a ceasefire that could wind down the 14-month war in Gaza and bring home dozens of people held hostage there. But the sides have come close before, only to have talks collapse over various disagreements. This round of negotiations also faces hurdles.
