Hamas is claiming responsibility Friday for an attack on a bus near an Israeli settlement in the West Bank, which has left at least eight injured, reports say.

Four people were injured by gunfire, three of them seriously, in Israel Friday after a Hamas gunman started shooting at a bus in the occupied West Bank city of Ariel, according to authorities.

"We are following what is happening in the West Bank in terms of serious violations of the occupation," Hamas spokesperson Ghazi Hamad told Newsweek.

CAIRO, Nov 29 (Reuters) - Israeli military strikes killed at least 40 Palestinians overnight and on Friday in the Gaza Strip, medics said, as efforts to revive Gaza ceasefire talks received a boost with officials from the Palestinian group Hamas headed to Cairo for a new round of talks.

Hamas said it was open to efforts to bring an end to its 13-month-old war with the Jewish state in Gaza as senior officials hailed the Israel-Hezbollah agreement.
