The attacks come days after Trump says Putin had "very strongly" promised response to Ukraine "Spider web" attack.

PRYLUKY, Ukraine (AP) — At least five people, including a 1-year-old child, his mother and grandmother, were killed Thursday in a nighttime Russian drone attack on the northern Ukrainian city of Pryluky, officials said.

But halting progress, ever-more deadly drone attacks and unmoving negotiating positions seem to have taken their toll. On Thursday, Trump used a striking analogy to concede the warfare was nowhere near over, and that he did not, at that moment, feel it was best to intervene.
