By Richard Balmforth and Anton Zverev KIEV/DONETSK Ukraine (Reuters) - Ukraine said on Monday its forces had ended a rebel blockade of a strategic airport in the east as it traded charges and threats with Russia over violations of their joint border during a weekend of fierce military combat. Ukraine's military said its warplanes had inflicted heavy losses on the pro-Russian separatists during air strikes on their positions, including an armored convoy which Kiev said had crossed the border from Russia. Ukrainian President Petro Poroshenko's office said Kiev would present documentary proof of incursions from Russia to the international community via diplomats on Monday.

Hamas, the Islamist group which runs Gaza, said its armed wing had sent several drones to carry out "special missions" deep inside Israel - a development which, if confirmed, would mark a step up in the sophistication of its arsenal. More than 166 Palestinians, most of them civilians, have been killed, Gaza health officials said, in seven days of fighting that has shown no sign of ending. Israeli aircraft and naval gunboats attacked 204 targets in the Gaza Strip overnight, said the army, in the worst flare-up in Israeli-Palestinian violence in almost two years.
