The MiG-31, considered one of the best fighters in the world, can carry guided missiles with a range of more than 200 kilometres (125 miles) and is capable of striking 24 different targets simultaneously, Yediot Aharonot said.

"This information is more concerning when put in the context of massive armaments purchases made recently by the Syrians," Yuval Steinitz, an MP from Israel's right-wing opposition Likud party, was quoted as telling the daily.

"If Syria acquires the MiG-31 we can no longer rule out the idea that this country is preparing for war," said Steinitz, a former chairman of Israel's defence and foreign affairs parliamentary committee.

A Russian newspaper reported on Tuesday that Russia has begun delivering five MiG-31E interceptors to Syria as part of an agreement reached this year, and that Moscow also plans to sell Damascus its MiG-29M/M2 dual role fighters.
