Israel launched a strike targeting Hamas’ leadership in Qatar on Tuesday, officials said, further widening its campaign against the militant group. Qatar has served as a key negotiator in efforts to end the conflict in the Gaza Strip, and it was unclear if the attack would stall those efforts. U.N. Secretary General Antonio Guterres condemned the attack Tuesday, saying “all parties must work towards achieving a permanent ceasefire, not destroying it.” An Israeli military spokesman said Israel’s air force carried out the strike.
