ISRAELI FORCES SEIZE RAFAH CROSSING, CEASEFIRE TALKS ON EDGE

In Israeli tank brigade seized control of Gaza's vital Rafah border crossing Tuesday as Israel brushed off urgent warnings from close allies and launched an incursion into the southern city even as cease-fire negotiations with Hamas remained on a knife's edge.

The U.N. warned of a potential collapse of the flow of aid to Palestinians from the closure of Rafah and the other main crossing into Gaza, Kerem Shalom, at a time when officials say northern Gaza is experiencing "fullblown famine." The Israeli foray overnight came after hours of whiplash in the now 7-month-old Israel-Hamas war, with the militant group saying Monday it accepted an EgyptianQatari mediated cease-fire proposal. Israel, however, insisted the deal did not meet its core demands.

The high-stakes diplomatic moves and military brinkmanship left a glimmer of hope alive if only barely - for a deal to bring at least a pause in the war, which has killed more than 34,700 Palestinians, according to local health officials, and has devastated the Gaza Strip.

By capturing Rafah, Israel gained full control over the entry and exit of people and goods for the first time since it withdrew soldiers and settlers from Gaza in 2005, though it has long maintained a blockade of the coastal enclave in cooperation with Egypt.

The incursion appeared to be short of the full-fledged offensive into Rafah that Israel has planned and might have been a pressure tactic in the cease-fire talks.
