FRANKFURT, Aug 12 (Reuters) - Germany's Lufthansa Group

has extended its suspension of flights to Tel Aviv,

Tehran, Beirut, Amman and Erbil up to and including Aug. 21, the

airline said on Monday, amid fears of an escalation in conflict

in the Middle East.

Lufthansa will not be using Iranian and Iraqi airspace

during that period, it said in an emailed statement.
