LONDON, Oct 9 (Reuters) - Israel's El Al will run more flights to take reservists back to Israel to help in the largest mobilisation in the country's history following an attack by Hamas militants over the weekend, a spokesperson for the airline said on Monday

Israel said on Monday it had called up an unprecedented 300,000 reservists and warned residents of the Gaza Strip to evacuate in a sign it could be planning a ground assault in response.

Fighters from the Islamist group killed 700 Israelis and abducted dozens in Saturday's attacks, the deadliest such incursion in decades, prompting Israel to retaliate by pounding the Palestinian enclave of Gaza.

The El Al spokesperson added that no flights had been cancelled and that many of the airline's planes to and from Israel were full.

El Al is increasing flights as most major carriers cancel or offer a reduced service to Israel after the surprise attack by Hamas. (Reporting by Joanna Plucinska Writing by Charlie Devereux Editing by Jon Boyle and Mark Potter)
