The Ukrainian air force says Russia launched more than 100 Shahed and decoy drones at Ukraine in nighttime attacks, after the Kremlin rejected an unconditional 30-day ceasefire in the more than 3-year war.

Russia is "completely ignoring" a 30-day ceasefire proposed by Ukraine and European powers that was to have begun on Monday, Ukrainian Foreign Minister Andrii Sybiha said.

Ukraine's air force reported an overnight Russian attack involving more than 100 drones, as Russia's President Vladimir Putin rejected Ukrainian President Volodymyr Zelensky 's proposal of an immediate 30-day ceasefire.

The agreement to release Edan Alexander came after talks between Washington and Hamas that did not include Israel.

Israel has not agreed to any ceasefire or release of prisoners with Hamas, but only to a safe corridor to allow the release of Israeli-American hostage Edan Alexander, Prime Minister Benjamin Netanyahu said on Monday.

Hamas says Edan Alexander, the last living American hostage in Gaza, will be released as part of efforts to establish a ceasefire, reopen crossings into the Israeli-blockaded territory and resume the delivery of aid.
