Israel is considering sending Soviet and Russian-made weapons captured in Lebanon to Ukraine, with signs transfers may be under way.

Israel reportedly met with Ukrainian diplomats on Tuesday to discuss a weapons transfer. Since then, US military cargo planes have been tracked flying from Israel to an airbase in eastern Poland.

“There are signs that Israel has begun supplying Ukraine with Soviet and Russian-made weapons,” Two Majors, a pro-Russia military blog on the Telegram social messaging site, told its 1.2 million subscribers on Sunday.

It posted photos of dozens of shoulder-mounted missiles laid out on hard-baked ground, as well as two screengrabs of a US military plane flying from Ramstein airbase in Germany to Hatzerim airbase in Israel and then to Rzeszów in Poland, near the border with Ukraine.
